ABSTRACT:
The performance of a host adapter integrated circuit is enhanced by storing blocks of information for SCSI I/O target commands, i.e, hardware request blocks, in a structure external to the host adapter integrated circuit. Since the number of blocks that is stored in the external structure is typically significantly greater than the number of blocks that can be stored in onboard registers of the host adapter integrated circuit, a high speed method for retrieving information from a particular block within the external structure is provided so that the appropriate block of information can be passed to the host adapter integrated circuit without delays associated with serially scanning through all of the blocks. Several structures are used in the external memory to manage the hardware request blocks. The structures include a hardware request block array, a hardware request block address array, a queue-in FIFO structure, a queue-out FIFO structure and a busy targets table.
