# tinycoral: reconstructing the Coral Edge TPU instruction set and USB runtime

> tinycoral reconstructs the Google Coral Edge TPU instruction set and USB runtime for a tinygrad backend. It includes decoded instruction layouts, a code generator, DarwiNN executable handling and a Python driver for firmware upload, register access and DMA transfers; the author reports byte-identical generated programs against Google's compiler for supported operations.
