The BK-3719 is designed to interface between a host system and a storage controller, either solid state or rotating media. The Serial ATA (SATA) core decodes incoming host commands and sets up the proper interrupts and status for the local microprocessor to handle ATA and ATAPI commands. Data transfer commands can be automated for full data transfer with minimal firmware support.
