GPUASIC

GPUASIC is a term used in open-source hardware and education to describe small, programmable GPU cores implemented for FPGA prototyping. It is not a single, official project; rather, multiple independent endeavors have used the name to designate lightweight GPU-like cores or to discuss a class of simple, shader-capable devices. The lack of a single canonical specification means that specific features vary by implementation.

Typical goals of GPUASIC efforts include illustrating GPU architecture, enabling experimentation with a modular shader pipeline, and providing a portable, easily simulated core for teaching or research. Most designs use hardware description languages such as Verilog or VHDL and are paired with a host interface and a minimal memory system. The shader units may execute a tiny, custom instruction set and support basic vertex or fragment processing, texture handling, and color output, but scale and performance are intentionally limited.

Applications are primarily educational demonstrations, hobbyist FPGA projects, and academic explorations of GPU design trade-offs. They are not intended for production-ready graphics or high-performance workloads, and emphasize simplicity and understandability over feature completeness.

Notes: the term GPUASIC blends GPU and ASIC concepts, but most references describe FPGA-implementable cores rather than commercial ASIC designs. For specifics, consult the documentation of the individual project or repository named GPUASIC.
