But he had previously designed a CPU in two weeks. The GPU took the same amount of time to develop.
The engineer detailed the entire process in his Twitter thread and admitted that designing the GPU was much more difficult than he expected.
Currently the project is a chip layout written in Verilog and successfully verified by the OpenLane EDA program.
However, in the coming months, the processor will be sent to production via the Tiny Tapeout 7 service, thus turning it into a real chip.
According to Adam, he initially realized that the project would require significant preparation because he was building a GPU from scratch without using off-the-shelf solutions. Their previous concerns about the difficulty of learning GPUs due to the dominance of proprietary technologies were completely justified.
