Abstract
A hard disk controller integrated circuit of a SCSI target device comprises a dedicated command descriptor block 'CDB' parsing state machine. The dedicated CDB parsing state machine parses incoming six-byte, ten-byte and twelve-byte SCSI command descriptor blocks and writes information from corresponding fields in the six-byte, ten-byte and twelve-byte SCSI command descriptor blocks into predetermined memory locations. In some embodiments, there are sixteen such predetermined memory locations which together comprise a 16.times.8 register file. A microprocessor coupled to the hard disk controller integrated circuit is therefore relieved of the burden of parsing incoming SCSI command descriptor blocks.
