Mi-V RISC-V Soft CPUs

Mi‑V RISC‑V Soft CPU Ecosystem for FPGA-Based Embedded Systems

We offer a comprehensive ecosystem of software tool chains and IP cores for FPGA designs. Mi-V RV32 RISC-V soft CPUs are available for PolarFire^® SoC, PolarFire^®, RTG4™, SmartFusion^® 2 and IGLOO^® 2 FPGAs with complete design support through Libero^® SoC Design Suite. The Eclipse-based SoftConsole IDE contains a development environment, a Renode emulation platform, GCC compiler and debugger needed for C/C++ embedded firmware development.

The Libero SoC Design Suite and SoftConsole development environments provide all the required tools to integrate Mi-V soft CPUs in our FPGAs and develop, test and debug embedded firmware.
