Notice

Here is RIOS Advanced Microprocessor Design Course Lab Template.

Your RTL and C model should be placed in riosclass_template/verilog and riosclass_template/cmodel.

Your lab report should be placed in riosclass_template/rpt.

We use this template for lab 1, lab 2, lab 3, final project and OpenMPW precheck.

Lab 1 Notice

The RTL code path: riosclass_template\verilog\rtl\lab_1\src

GreenRio, AKA hehe, is a small RISC-V CPU.

For Lab 1:

RTL

1. "riosclass_template\verilog\rtl\lab_1\src" is the GreenRio RTL source code path. Some tests have been passed. You will use all files in 'core_empty'(except 'mmu'), 'cache', 'params.vh', 'bus_arbiter.v' and 'hehe.v' for simulation and logic synthesis.

   1. core_empty: the function_unit modules, pipeline, and core_empty top RTL codes; 'core_empty' means that the source codes here are the pure core parts of the CPU, excluding cache and sram.

   2. cache: the cache parts of CPU; the sram is instantiated at the top of the cache module.

   3. bus_arbiter: communication bus between SoC and core.

   4. hehe: the top of GreenRio CPU.

2. Other files should not be used in lab1, but will be used in later labs.

3. You can access the spec documentaion at riosclass_template\spec\HeHecore.md.
