SHAKTIMAAN: SHAKTI Multiply-Accumulate Accelerator Network

SHAKTIMAAN is a synthesizable and parameterized open source DNN accelerator. The accelerator contains a systolic array and a SIMD engine to perform the expensive DNN computations. The entire code is written in Bluespec and is compatible with Shakti C-Class processor.

Dependencies

1. Installing Bluespec
2. Installing verilator

Using SHAKTIMAAN

Software compilation

In the first step, instructions for SHAKTIMAAN are generated using a separate compilation process. More details to follow. Instructions are compiled and stored in RAM, which is loaded when the testbench is initiated directly from code.mem. More to follow.

Configuration

A testbench is available in src/Soc.bsv which instantiates the accelerator and runs a single trace of instructions. All configurations can be changed adhering to the provisos required for compilation of Bluespec files and can be changed in src/Soc.bsv. Non configurable parameters, such as ISA definitions, are defined in src/commons/systolic.defines.

Verilog generation

1. cd src
2. make generate_verilog - generates Verilog files from Bluespec for all files.

Simulation

1. cd src
2. make generate_verilog
3. make link_verilator - generates a binary bin/out which simulates the array.
