eGPU: A 750 MHz Class Soft GPGPU for FPGA

The "G" in "GPU" or the second "G" in "GPGPU" stands for "graphics". The paper describes a compute-oriented processor that doesn't appear to contain any gfx-specific hardware.

For instance, in conventional GPUs, there is dedicated hardware for rasterizing the pixels covered by a triangle; there is dedicated hardware for doing texture map calculations and sample filtering. The instruction set disclosed in the paper doesn't contain anything to help accelerate those tasks. With enough code I'm sure one could get it to draw something, but it will be notably inefficient while doing so.

Also, the 'e' in eGPU usually means that the card is housed externally to the rest of the computer - in its own enclosure.

They don't actually explain anywhere in their paper what 'eGPU' means. Is it 'emulated'? I thought circuits implemented in FPGAs are not considered emulation?

I'm tinking the e means embedded
