-- Run on the HiFive1 board with the command `make upload TARGET=freedom-e300-hifive1 PROGRAM=dhrystone`.
- This will take a few minutes. Sample output is provided below.

-#### CoreMark ####
-
-We cannot distribute the CoreMark benchmark, but following are instructions
-to download and run the benchmark on the HiFive1 board:
-
-- Download CoreMark from EEMBC's web site and extract the archive from
- http://www.eembc.org/coremark/download.php.
-- Copy the following files from the extracted archive into the
- `software/coremark` directory in this repository:
- - `core_list_join.c`
- - `core_main.c`
- - `coremark.h`
- - `core_matrix.c`
- - `core_state.c`
- - `core_util.c`
-- Compile the benchmark with the command `make software PROGRAM=coremark`.
-- Run on the HiFive1 board with the command `make upload PROGRAM=coremark`.
-- Divide the reported Iterations/Sec by the reported core frequency in MHz to
- obtain a CoreMarks/MHz value.

-// The below gives a mapping between global interrupt
-// sources and their number. Note that on the coreplex
-// deliverable, the io_global_interrupts go directly into
-// the PLIC. The evaluation image on the FPGA mimics a
-// system with peripheral devices which are driving the
-// global interrupt lines.
-// So, on this image, in order to get an interrupt from
-// e.g. pressing BUTTON_0:
-// 1) Steps which are external to the delivery coreplex:
-// a) The corresponding GPIO pin must be configured as in input
-// b) The "interrupt on fall" bit must be set for the GPIO pin
-// 2) Steps which would also need to be performed for the delivery coreplex:
-// a) The corresponding global interrupt, priority, and threshold must be configured in the PLIC.
-// b) The external interrupt bit must be enabled in MSTATUS
-// c) Interrupts must be enabled globally in the core.
-
-// Any of the above GPIO pins can be used as global interrupt
-// sources by adding their offset to the INT_GPIO_BASE.
-// For example, the buttons are shown here:
-
-#define INT_DEVICE_BUTTON_0 (GPIO_INT_BASE + BUTTON_0_OFFSET)
-#define INT_DEVICE_BUTTON_1 (GPIO_INT_BASE + BUTTON_1_OFFSET)
-#define INT_DEVICE_BUTTON_2 (GPIO_INT_BASE + BUTTON_2_OFFSET)
-#define INT_DEVICE_BUTTON_3 (GPIO_INT_BASE + BUTTON_3_OFFSET)
-
-// In addition, the Switches are mapped directly to
-// the PLIC (without going through the GPIO Peripheral).
-
-#define INT_EXT_DEVICE_SW_0 (EXTERNAL_INT_BASE + 0)
-#define INT_EXT_DEVICE_SW_1 (EXTERNAL_INT_BASE + 1)
-#define INT_EXT_DEVICE_SW_2 (EXTERNAL_INT_BASE + 2)

-Benchmarking
-============
-
-The Dhrystone and CoreMark benchmarks are still only supported by the Legacy
-Freedom E SDK. When we port the benchmarks to Freedom Metal, we will update
-this section to describe the updated build steps.
-
-Dhrystone
----------
-
-After setting up the software and debug toolchains, you can build and
-execute everyone's favorite benchmark as follows:
-
-- Compile the benchmark with the command ``make software TARGET=freedom-e300-hifive1 PROGRAM=dhrystone LINK_TARGET=dhrystone``. Note that a slightly different linker file is used for Dhrystone which stores read only data in DTIM instead of external flash.
-- Run on the HiFive1 board with the command ``make upload TARGET=freedom-e300-hifive1 PROGRAM=dhrystone``.
- This will take a few minutes. Sample output is provided below.
-- Compute DMIPS by dividing the Dhrystones per Second result by 1757, which
- was the VAX 11/780's performance. In the example below, 729927 / 1757 =
- 415 DMIPS.
-- Compute DMIPS/MHz by dividing by the clock rate: in the example below,
- 415 / 268 = 1.55 DMIPS/MHz.
-
-.. code-block:: none
-
- core freq at 268694323 Hz
-
- Dhrystone Benchmark, Version 2.1 (Language: C)
-
- <snip>
-
- Microseconds for one run through Dhrystone: 1.3
- Dhrystones per Second: 729927.0
-
-CoreMark
---------

-We cannot distribute the CoreMark benchmark, but following are instructions
-to download and run the benchmark on the HiFive1 board:
-
-- Download CoreMark from EEMBC's web site and extract the archive from
- `<http://www.eembc.org/coremark/download.php>`_.
-- Copy the following files from the extracted archive into the
- ``software/coremark`` directory in this repository:
-
- - ``core_list_join.c``
- - ``core_main.c``
- - ``coremark.h``
- - ``core_matrix.c``
- - ``core_state.c``
- - ``core_util.c``
-
-- Compile the benchmark with the command ``make software PROGRAM=coremark``.
-- Run on the HiFive1 board with the command ``make upload PROGRAM=coremark``.
-- Divide the reported Iterations/Sec by the reported core frequency in MHz to
- obtain a CoreMarks/MHz value.

-E2 Core IP Eval Kit 'clic_vectored' demo.\n\
-This demo uses buttons 0, 1, and 2 on the\n\
-Arty board to trigger vectored clic interrupts.\n\
-The higher the button number, the higher the\n\
-interupt priority. Button 0's handler runs for\n\
-10 seconds, button 1's for 5, and button 2's for 1.\n\
-Preemption is enabled so that higher priority\n\
-interrupts can be triggered while in low priority\n\
-handlers. The demo also uses the CLIC's software\n\
-interrupt to pend a lower priority interrupt from\n\
-button 2's handler.\n\
-\n\
-Note the buttons are wired directly into the local\n\
-interrupts, so a given interrupt will stay asserted\n\
-as long as the button is being pushed.\n\
-\n\
-This demo works for both the E20 and E21 FPGA\n\
-as long as CLIC_CONFIG_BITS matches the desired\n\
-core.\n\

- * "DHRYSTONE" Benchmark Program
- * -----------------------------
- *
- * Version: C, Version 2.1
- *
- * File: dhry.h (part 1 of 3)
- *
- * Date: May 25, 1988
- *
- * Author: Reinhold P. Weicker
- * Siemens AG, AUT E 51
- * Postfach 3220
- * 8520 Erlangen
- * Germany (West)
- * Phone: [+49]-9131-7-20330
- * (8-17 Central European Time)
- * Usenet: ..!mcsun!unido!estevax!weicker
- *
- * Original Version (in Ada) published in
- * "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
- * pp. 1013 - 1030, together with the statistics
- * on which the distribution of statements etc. is based.
- *
- * In this C version, the following C library functions are used:
- * - strcpy, strcmp (inside the measurement loop)
- * - printf, scanf (outside the measurement loop)
- * In addition, Berkeley UNIX system calls "times ()" or "time ()"
- * are used for execution time measurement. For measurements
- * on other systems, these calls have to be changed.
- *
- * Collection of Results:
- * Reinhold Weicker (address see above) and
- *
- * Rick Richardson
- * PC Research. Inc.
- * 94 Apple Orchard Drive
- * Tinton Falls, NJ 07724
- * Phone: (201) 389-8963 (9-17 EST)
- * Usenet: ...!uunet!pcrat!rick
- *
- * Please send results to Rick Richardson and/or Reinhold Weicker.
- * Complete information should be given on hardware and software used.
- * Hardware information includes: Machine type, CPU, type and size
- * of caches; for microprocessors: clock frequency, memory speed
- * (number of wait states).
- * Software information includes: Compiler (and runtime library)
- * manufacturer and version, compilation switches, OS version.
- * The Operating System version may give an indication about the
- * compiler; Dhrystone itself performs no OS calls in the measurement loop.
- *
- * The complete output generated by the program should be mailed
- * such that at least some checks for correctness can be made.
- *
- ***************************************************************************
- *
- * History: This version C/2.1 has been made for two reasons:
- *
- * 1) There is an obvious need for a common C version of
- * Dhrystone, since C is at present the most popular system
- * programming language for the class of processors
- * (microcomputers, minicomputers) where Dhrystone is used most.
- * There should be, as far as possible, only one C version of
- * Dhrystone such that results can be compared without
- * restrictions. In the past, the C versions distributed
- * by Rick Richardson (Version 1.1) and by Reinhold Weicker
- * had small (though not significant) differences.
- *
- * 2) As far as it is possible without changes to the Dhrystone
- * statistics, optimizing compilers should be prevented from
- * removing significant statements.
- *
- * This C version has been developed in cooperation with
- * Rick Richardson (Tinton Falls, NJ), it incorporates many
- * ideas from the "Version 1.1" distributed previously by
- * him over the UNIX network Usenet.
- * I also thank Chaim Benedelac (National Semiconductor),
- * David Ditzel (SUN), Earl Killian and John Mashey (MIPS),
- * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley)
- * for their help with comments on earlier versions of the
- * benchmark.
- *
- * Changes: In the initialization part, this version follows mostly
- * Rick Richardson's version distributed via Usenet, not the
- * version distributed earlier via floppy disk by Reinhold Weicker.
- * As a concession to older compilers, names have been made
- * unique within the first 8 characters.
- * Inside the measurement loop, this version follows the
- * version previously distributed by Reinhold Weicker.
- *
- * At several places in the benchmark, code has been added,
- * but within the measurement loop only in branches that
- * are not executed. The intention is that optimizing compilers
- * should be prevented from moving code out of the measurement
- * loop, or from removing code altogether. Since the statements
- * that are executed within the measurement loop have NOT been
- * changed, the numbers defining the "Dhrystone distribution"
- * (distribution of statements, operand types and locality)
- * still hold. Except for sophisticated optimizing compilers,
- * execution times for this version should be the same as
- * for previous versions.
- *
- * Since it has proven difficult to subtract the time for the
- * measurement loop overhead in a correct way, the loop check
- * has been made a part of the benchmark. This does have
- * an impact - though a very minor one - on the distribution
- * statistics which have been updated for this version.
- *
- * All changes within the measurement loop are described
- * and discussed in the companion paper "Rationale for
- * Dhrystone version 2".
- *
- * Because of the self-imposed limitation that the order and
- * distribution of the executed statements should not be
- * changed, there are still cases where optimizing compilers
- * may not generate code for some statements. To a certain
- * degree, this is unavoidable for small synthetic benchmarks.
- * Users of the benchmark are advised to check code listings
- * whether code is generated for all statements of Dhrystone.
- *
- * Version 2.1 is identical to version 2.0 distributed via
- * the UNIX network Usenet in March 1988 except that it corrects
- * some minor deficiencies that were found by users of version 2.0.
- * The only change within the measurement loop is that a
- * non-executed "else" part was added to the "if" statement in
- * Func_3, and a non-executed "else" part removed from Proc_3.
- *
- ***************************************************************************
- *
- * Defines: The following "Defines" are possible:
- * -DREG=register (default: Not defined)
- * As an approximation to what an average C programmer
- * might do, the "register" storage class is applied
- * (if enabled by -DREG=register)
- * - for local variables, if they are used (dynamically)
- * five or more times
- * - for parameters if they are used (dynamically)
- * six or more times
- * Note that an optimal "register" strategy is
- * compiler-dependent, and that "register" declarations
- * do not necessarily lead to faster execution.
- * -DNOSTRUCTASSIGN (default: Not defined)
- * Define if the C compiler does not support
- * assignment of structures.
- * -DNOENUMS (default: Not defined)
- * Define if the C compiler does not support
- * enumeration types.
- * -DTIMES (default)
- * -DTIME
- * The "times" function of UNIX (returning process times)
- * or the "time" function (returning wallclock time)
- * is used for measurement.
- * For single user machines, "time ()" is adequate. For
- * multi-user machines where you cannot get single-user
- * access, use the "times ()" function. If you have
- * neither, use a stopwatch in the dead of night.
- * "printf"s are provided marking the points "Start Timer"
- * and "Stop Timer". DO NOT use the UNIX "time(1)"
- * command, as this will measure the total time to
- * run this program, which will (erroneously) include
- * the time to allocate storage (malloc) and to perform
- * the initialization.
- * -DHZ=nnn
- * In Berkeley UNIX, the function "times" returns process
- * time in 1/HZ seconds, with HZ = 60 for most systems.
- * CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY
- * A VALUE.
- *
- ***************************************************************************
- *
- * Compilation model and measurement (IMPORTANT):
- *
- * This C version of Dhrystone consists of three files:
- * - dhry.h (this file, containing global definitions and comments)
- * - dhry_1.c (containing the code corresponding to Ada package Pack_1)
- * - dhry_2.c (containing the code corresponding to Ada package Pack_2)
- *
- * The following "ground rules" apply for measurements:
- * - Separate compilation
- * - No procedure merging
- * - Otherwise, compiler optimizations are allowed but should be indicated
- * - Default results are those without register declarations
- * See the companion paper "Rationale for Dhrystone Version 2" for a more
- * detailed discussion of these ground rules.
- *
- * For 16-Bit processors (e.g. 80186, 80286), times for all compilation
- * models ("small", "medium", "large" etc.) should be given if possible,
- * together with a definition of these models for the compiler system used.
- *
- **************************************************************************
- *
- * Dhrystone (C version) statistics:
- *
- * [Comment from the first distribution, updated for version 2.
- * Note that because of language differences, the numbers are slightly
- * different from the Ada version.]
- *
- * The following program contains statements of a high level programming
- * language (here: C) in a distribution considered representative:
- *
- * assignments 52 (51.0 %)
- * control statements 33 (32.4 %)
- * procedure, function calls 17 (16.7 %)
- *
- * 103 statements are dynamically executed. The program is balanced with
- * respect to the three aspects:
- *
- * - statement type
- * - operand type
- * - operand locality
- * operand global, local, parameter, or constant.
- *
- * The combination of these three aspects is balanced only approximately.
- *
- * 1. Statement Type:
- * ----------------- number

- * component), only the final data type on the access path is counted.

- * -------------------
- * number approximate

- * --- -------
- * 242 100.0 %
- *
- *
- * The program does not compute anything meaningful, but it is syntactically
- * and semantically correct. All variables have a value assigned to them
- * before they are used as a source operand.
- *
- * There has been no explicit effort to account for the effects of a
- * cache, or to balance the use of long or short displacements for code or
- * data.

-// This is the 'bootloader' which ships on HiFive1 boards,
-// at SPI Flash location 0x20000000.
-// HiFive1 boards have code burned into their OTP which ends with
-// a jump to 0x20000000. The Freedom E SDK and the Arduino IDE
-// linker scripts cause user programs to be compiled and
-// flashed at 0x20400000. Therefore, this code ultimately jumps
-// to 0x20400000, while attempting to leave the machine state as close
-// to its reset state as possible.
-//
-// When compiled in the freedom-e-sdk environment, this code will
-// be compiled as a user program at 0x20400000, so will continuously jump to itself.
-// It is provided in the freedom-e-sdk mostly for reference purposes, so
-// users know what is running on their board. Replacing the bootloader
-// at 0x20000000 is not currently supported by the SDK.
-//
-// These are the instructions for the user of this program, from the
-// HiFive1 Getting Started Guide:
-//
-// This program is designed to allow quick boot, but
-// also a "safe" reboot option if a "bad" program
-// is flashed into the HiFive1's SPI Flash. A "bad" program
-// is one which makes it impossible for the programmer
-// to communicate with the HiFive1. For example, a program which
-// disables FE310's active clock, or which puts the FE310 to sleep
-// with no way of waking it up. Bad programs can always be restarted using
-// the RESET button, and using the "safe" bootloader can be halted
-// before they perform any unsafe behavior.
-//
-// To activate "normal" boot mode, press the RESET button on
-// the HiFive1. After approximately 1s, the green LED will flash
-// for 1/2 second, then the user program will execute.
-//
-// To activate "safe" boot mode, press the RESET button. When
-// the green LED flashes, immediately press the RESET button again.
-// After 1 second, the red LED will blink. The user program will not
-// execute, and the programmer can connect. To exit "safe" boot mode,
-// press the RESET button a final time.
