WebRISC-V

WebRISC-V is a web-based graphical pipelined datapath simulation environment built for the RISC-V instruction set architecture. It is suitable for teaching how assembly level code is executed on the RISC-V pipelined architecture and for illustrating the Pipeline Architectural Elements.

WebRISC-V is online and ready for use

Features

  • 5-stage Graphical Pipeline 32/64-bit Simulator
    • Pipeline Schema taken and enhanced from Patterson's 'Computer Organization and Design: RISC-V Edition'
    • Visualize every Architectural Element and the Data and Control paths
    • Execute with or without Forwarding
    • Change the Branch Hazard handling using the Delay Slot
    • Keep track of the execution in the Pipeline
      • Instruction Memory | Data Memory | Registers
    • Show the execution trace with the Pipeline Table
    • Interact with the execution through implemented syscalls on the Console
  • Supported instructions are the full RV32I and RV64I Base Instruction Sets (excluding: fence) as well as the full RV32M and RV64M Standard Multiplication Extensions
    • List of supported instructions with small Verilog descriptions available
    • List of supported directives with small descriptions of meaning available
    • RISC-V Assembly simple examples available
