Intelligent SCSI-2/DMA processor

Image Number 5 for United States Patent #5721954.

A SCSI-2-and-DMA processor that has on a single integrated circuit a SCSI-2 interface for a SCSI-2 data bus that is at least two bytes wide and a DMA interface for a system data bus that is at least two bytes wide. This integrated circuit has an set of control registers and an on-chip processor such that the transfers involving SCSI-2 data transfers involving data words that have a width of at least two bytes can be processed and completed without burdening the remainder of the system. Substantially all that is needed of the system processor is to down load a very compact control program and then transfers between this integrated circuit and system RAM. The on-chip processor allows chaining of random length blocks of contiguous address data by using a chain mode of transfer which also pairs up any odd residue with a portion of the first word of the next block in the chain using on-chip processing.
