GreenPAK design files

This folder contains design files for SLG46824 programmable logic device. It is optionally used on ZuluSCSI V1.1 to speed up access to SCSI bus. This applies to asynchronous transfers only

What this logic does is implement the REQ / ACK handshake in hardware. The CPU only has to write new data to the GPIO, and the external logic will toggle REQ signal quickly.
