That is a cryptography accelerator ASIC built utilizing the SKY130 (130nm) method node, to become taped out around the Google/Skywater/efabless open up-source MPW shuttle. It incorporates hardware implementations of cores for AES128/AES256 and SHA256, as well as an experimental VGA-based mostly sport demo (Additionally, it incorporates the "caravel" debug-harness/padframe that is getting used During this tapeout). The eventual intention of the job is to employ it for embedded/IoT safety purposes.
