mingpu

Mingpu is an extremely minimal GPU architecture that I wrote for fun and also to learn basic hardware design. Though, it does not have the "G" in "GPU" (yet) - it does not do any graphics, but rather focuses on pure parallel SIMD compute.

Architecture

Currently, Mingpu includes:

• A control unit to dispatch instructions to compute cores.
• 80 compute cores each with:
  • 1 register/accumulator.
  • 16-bit word size in register and memory.
  • 8-bit opcode and 8-bit operand.
  • 512 bytes (256 16-bit words) of local mem each core.
  • A minimal 6-op ISA - NOP, ADD (signed), MUL (signed), LOAD, STORE, HALT.
• 1 8-bit program counter for all cores, which means 256 instructions (512 bytes) for kernel maximum.

Setup

I currently use Icarus Verilog for development of this project, so have it installed and you are good to go.

Run testbench

make sim

Configuration

You can configure the gpu (number of cores, local mem size, data width, etc.) in ./rtl/gpu_pkg.sv.

Todos

• Rethink better arch overall, currently this is a very naive arch and implementation from me. Though it should always stay minimal.
• Integration with real hardware, possibly an EBAZ4205, which should come with:
  • Ethernet communication code.
  • Driver.
  • Assembler.
