摘要： A disk controller for a hard disk drive includes a disk formatter interfaced via an NRZ bus to a read channel for the disk. The disk formatter includes an LFSR accumulator coupled to the NRZ bus, as well as an LSFR generator that generates synthetic test data for the disk formatter. Under control of a test flag which signifies a test mode, the LSFR generator generates synthetic test data, which is used by the disk formatter to drive the NRZ bus. The LSFR accumulator accumulates data on the NRZ bus, together with data on servo information and sector information. An interface is provided through which the accumulated information is provided to test equipment, for offline analysis of the accumulated information, so as to confirm proper operation of the disk subsystem and/or to detect failures therein.

摘要： A system for controlling and routing messages and data received from dual system busses, through a bus interface unit, to a protocol translation logic means and to a processor in a central processing module connected onto a dual system bus network. The processor operates at a first clock rate and on a single-word communication protocol while the translation logic means operates at a second rate and multiple-word communication protocol. The processor and translation logic are destination modules which receive the benefit of the receiving control logic system. The receiving control logic system also services external modules on the system bus in order to receive data and control the routing of data to the destination modules. Destination modules which are busy and not ready will cause the system to inform the external transmitting modules that they must retry their transmission. The system also checks the quality of the data on the system busses and informs the processor when errors have been incurred, in addition to informing the originating modules when a transmitted message has been completed.

摘要： A message transfer system between digital modules where two or more digital modules operate on separate and different message lengths and clock frequencies and where, temporary storage buffer (translator unit) holds messages being transferred between the different digital modules and acts as a speed matching and word length matching buffer unit to permit compatible transfer of message words. Also, the transfer system recognizes when requests are outstanding from both digital modules and can discard a message from a requesting module. Each of the two or more separate digital modules is serviced by dual system busses providing for redundancy of data transfer operations.

摘要： A system includes a receive module, a control module and a read module. The receive module receives a first block that includes first data, a first cyclic redundancy check (CRC) checksum, and a first error-correcting code (ECC) value. The first CRC checksum and the first ECC value include a logical block address (LBA). The control module generates a first derived CRC checksum based on the first data. The first derived CRC checksum does not include the LBA. The read module reads a second block from a parity disk. The second block includes parity data, a second CRC checksum, and a second ECC value. The second CRC checksum and the second ECC value include the LBA.

摘要： A User bus lockout prevention mechanism for use in a time-shared bus, multiple bus User, computer architecture where bus Users have private cache systems which perform a cache cycle when a WRITE TO MEMORY instruction occurs on the bus to determine if data cached from main memory has been overwritten in main memory. A User can be locked out from use of the bus if a synchronism occurs between repetitive cache cycles and periodicity of the request Retry mechanism of the User. Bus lockout is prevented by controlling the Retry mechanism of the User to retry requests in accordance with a sequence of varying retry wait intervals. The sequence comprises bursts of short wait intervals interleaved with long wait intervals, the sequence beginning with a burst of short wait intervals. The wait interval durations of the first and second occurring bursts are interleaved with respect to each other. The second occurring long wait is longer than the first occurring long wait. The sequence is terminated upon bus grant.

摘要： A processor cache memory system utilizes separate cache controllers for independently managing even and odd input address requests with the even and odd address requests being mapped into the respective controllers. Each cache controller includes tag RAM for storing address tags, including a field for storing the least significant address bit, so that the stored tags distinguish between the odd and even addresses. Upon failure of a cache controller, both the even and odd addresses are directed to the operational controller and the stored least significant bit address tag distinguishes between the odd and even input addresses to appropriately generate HIT/MISS signals. The controllers include block address counter logic for generating respective even and odd invalidation addresses for simultaneously performing invalidation cycles thereon when both controllers are operational. When a controller fails, the block address counter logic generates both even and odd block invalidation addresses in the operational controller.
