The RVCore Project is a research and development project of the RISC-V soft processor highly optimized for FPGAs.

RVCoreP (RISC-V Core Pipelined version) is one of the RISC-V soft processor cores of the RVCore Project. It is an optimized RISC-V soft processor of five-stage pipelining.

RVCoreP supports the following FPGA boards!

• Nexys 4 DDR board with Xilinx Artix-7 FPGA
• Arty A7-35T board with Xilinx Artix-7 FPGA

The main specifications of RVCoreP are shown below:

• An optimized RISC-V soft processor
• Adopt RV32I of RISC-V as an instruction set architecture, which is the basic 32-bit integer instruction set
• Adopt five-stage pipelining
  • Instruction fetch (If)
  • Instruction decode (Id)
  • Instruction execution (Ex)
  • Memory access (Ma)
  • Write back (Wb)
• Apply three effective optimization methods to improve the operating frequency
  • Instruction fetch unit optimization including the pipelined branch prediction mechanism
  • ALU optimization
  • Data alignment and sign-extension optimization for data memory output
• Implemented in Verilog HDL
• Run RISC-V programs compiled with RV32I
  • By Verilog HDL simulation using Verilator or Icarus Verilog
  • On the FPGA boards including Xilinx Artix-7 FPGA
