A 750MHz-class soft GPGPU for FPGA

Uses logic rather than GPU IP in FPGA.

Jon Peddie

(Source: Secret Deer project, Blender) Researchers at Imperial College London developed a soft GPU (sGPU,) or eGPU, a specialized GPGPU architecture programmed onto an FPGA. This architecture maximizes the benefits of soft logic and embedded features, achieving high performance and balanced resource utilization. Their primary goal was to create a powerful soft processor capable of efficiently implementing complex FPGA system designs. The eGPU is based on a streaming multiprocessor (SM) model with 512 threads per SM and 16 scalar processors (SP) supporting both IEEE 754 FP32 and INT32 integer arithmetic. The researchers successfully demonstrated a single SM eGPU running at
