GHRD/GSRD Reference Design

The Golden System Reference Design (GSRD) and the Golden Hardware Reference Design (GHRD) comprise a collection of software and hardware components for developing various applications using the Lattice FPGA.

The Golden System Reference Design (GSRD) is a thoroughly tested known good design showcasing a system using FPGA based RISC-V soft CPU, intended to be used as a baseline project.

The GSRD is comprised of the following components:

• Golden Hardware Reference Design (GHRD)
• Reference RISC-V soft CPU software including:
  • Basic Bootloader
  • U-boot Bootloader
  • FreeRTOS Driver
  • FreeRTOS Sample applications

Golden Hardware Reference design (GHRD) is a hardware reference design that FPGA designers can use as a base starting point to create their own FPGA hardware design. It consists of key hardware building blocks like the RISC-V soft CPU, Flash controller, Scatter-Gather Direct Memory Access Controller and industry standard AXI4 interconnect.
