-The SiFive S76 Standard Core is a high-performance 64-bit embedded processor which is fully-compliant with the RISC-V ISA.
-
-The S76 is ideal for latency-sensitive applications in domains such as storage and networking that require 64-bit memory addressability (e.g. In-storage Compute, Edge Compute, 5G Modems, Object storage etc.)
-
-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 RV64IMAFDC core
-- 4 hardware breakpoints
-- Physical Memory Protection with 8 regions
-- 16 local interrupts signal that can be connected to off core complex devices
-- Up to 127 PLIC interrupt signals that can be connected to off core complex devices, with 7 priority levels
