-The SiFive E24 Standard Core is a high-performance microcontroller with hardware support for single-precision floating-point capabilities by implementing the RISC-V ISA’s F standard extension. The E24’s efficiency, coupled with hardware floating-point capabilities, make it exceptional at motor control, sensor fusion, and IoT applications.
-
-This core target is suitable with Verilog RTL for verification and running application software building on top of freedom-metal libraries. The target supports:
-
-- 1 hart with RV32IMAFC core
-- 4 hardware breakpoints
-- Physical Memory Protection with 4 regions
-
