摘要： A system for detecting transmission errors in a data transmission system includes a receiver for receiving a data packet transmitted thereto by a corresponding transmitter and transmitting the data packet to a destination device and an error detection device for receiving a plurality of protocol signals that control the operation of the transmitter and the receiver. The error detection device applies at least one predetermined rule to the protocol signals, wherein a violation of the at least one rule by the protocol signals indicates that an error in the transmission of the packet has occurred, and asserts an error signal when the at least one rule has been violated by the protocol signals. The system further includes a packet filtering device coupled to receive the error signal from the error detection device and the data packet from the receiver, wherein, upon receiving the asserted error signal, the packet filtering device terminates the transmission of the data packet to the destination device.

摘要： A system having a memory with a plurality of contiguous processor memory regions and a plurality of processors. Each one of such processors is associated with a corresponding one of the processor memory regions. Each one of such processors provides a plurality of sets of successive processor addresses. The addresses in each one of such sets has a successive series of used addresses and a successive series of reserve addresses. The last used address in each one of the sets is separated from the first used address in the next successive set of addresses by a gap of addresses, G. A common address translator is fed by virtual addresses and maps the virtual addresses fed thereto to the memory addresses, such mapping being in accordance with the gap G to map each one of the sets of used processor addresses provided by each of the processors into the corresponding one of the contiguous processor memory regions.

摘要： A computer storage system includes director boards which control transfer of data to and between a host computer, a system cache memory and a disk array. The directors are provided with features which enhance system performance and reliability. A hardware emulation controller permits a high performance processor to be used with existing system circuitry. A control store memory is organized with primary and secondary data areas and primary and secondary parity areas. Data is written to both the primary and secondary areas. A read request accesses data in the primary area and performs a retry in the secondary area in the event of a parity error. A power supply system includes on-board marginable power supplies to facilitate testing and power-up by-pass circuits for protection of sensitive circuitry. A system clock configuration employs primary and secondary clocks to ensure redundancy of synchronized timekeeping.

摘要： A system and method for determining data integrity as such data passes through a FIFO. A generator is provided for appending a bit in a predetermined bit location in each packet pushed into the FIFO in response clock signals. The appended bit is a function of the information pushed into the FIFO. A checker is provided for providing an indication of the information integrity in response to bits produced at an output of the FIFO in the predetermined bit location. In one embodiment, the generator is a parity generator and the checker is a parity checker. In one embodiment, during an initial test mode, one parity type is introduced into the FIFO by the parity generator and the opposite parity type is checked at the output of the FIFO by the parity checker to determine whether the parity checker is able to produce parity error signals. In another embodiment, the generator is a packet delimiter generator and the checker is a packet delimiter checker. In another embodiment, the generator is a frame delimiter generator and the checker is a frame delimiter checker.

摘要： A system and method wherein a bus arbiter grants access to a bus to bus-coupled clients in order to provide access to a memory resource shared by the clients in response to “address retry” conditions induced by such clients. The bus arbiter provides access to the bus in response to whether one of the requesting clients experienced an “address retry” condition during its previous bus access. If such an address retry condition was experienced during its previous bus access, the bus arbiter grants such one of the requesting clients access to the bus at the earliest opportunity. Otherwise, the bus arbiter provides bus access to the requesting one, or ones, of the clients based on criteria independent of “address retry” conditions being induced on the bus.
