U-interrupt

This is a zcu102 port for the implementation of RISC-V user interrupt extension, based on Rocket.

Introductions

If you clone the repository for the first time, you must update submodules recursively. You may follow the README to install a riscv toolchain.

Run the following scripts in the root directory to generate Rocket Chip verilog outputs.

make build

• What is user interrupt?
• System stack of Zynq FPGA, going top-down from RISC-V software to hardware layouts.
• Modifications to Rocket Chip to support user interrupt.
• Modifications to rCore to take advantage of new hardware features.
• Modifications to Linux for further design and evaluation.

Plans

• Get familiar with the process of hardware development on zcu102.
  • Port Rocket Chip to zcu102.
  • Boot rCore and Linux on Rocket Chip.
