摘要:
A peripheral equipment control LSI interposed between an SCSI bus connected to a main CPU and peripheral equipment such as a file device. The LSI is divided into two major blocks. One block recognizes an SCSI protocol ID signal sent over the SCSI bus. The other block generates a signal that causes the other block to leave a sleep state (low power dissipation mode). In a state in which a command is awaited from the main CPU, the peripheral equipment control LSI allows the block containing the ID recognition part to remain active while the other block is kept in the sleep state. On receiving an ID-based selected (access) signal from the main CPU, the LSI detects the start of an access operation and causes the other block to leave its sleep state and to become active.
