Abstract: A method for verifying the proper communication of data packets from an initiator device on a PCIe data bus to a target device on the data bus. A target-specific counter on the initiator is synchronized to an initiator-specific counter on the target with the same value. The initiator writes the value of the target-specific counter into the tag field of the packet header, and also writes an identifier of the initiator into the header. Then the initiator sends the packet to the target on the PCIe data bus. Upon receipt of the packet, the target reads the identifier and checks the value against the appropriate initiator-specific counter on the target. When the value is not equal to the initiator-specific counter on the target, then it generates an error message. An additional memory write with specific data is posted from the initiator to the target. A memory read is posted of the additional memory write location from the initiator to the target.

Abstract: The present invention is directed to determining the timing for a synchronous integrated circuit, the circuit including a multiplicity of clocked elements interconnected by signal paths. Predictions are formed for timing delays in said signal paths in the integrated circuit. A first such path is selected, wires are traced in the integrated circuit forming the path, hereinafter referred to as victim wires, and adjacent and crossing wires thereto, hereinafter referred to as aggressor wires, are determined. For each aggressor wire, the amount of electromagnetic coupling to the victim wires of the first path is determined. The aggressor wires are divided into a plurality of categories depending on the clocked timing of the aggressor wires in relation to the clocked timing of the victim wires.

Further, the present invention may provide an independent tool running under DOS without the presence of the PCI option ROM. Independent DOS executable module may be used to demonstrate the application for internal reviews.

Abstract: Skip logic is provided in a storage controller that informs a direct memory access (DMA) context list manager of consecutive ones and zeroes in a skip mask table. The DMA context list manager then manages data counters and location pointers based on the number of consecutive ones and the number of consecutive zeroes. For writes and non-cached reads, the number of zeroes is used to adjust a logical sector address without actually moving data. For cached reads, the number of zeroes is used to adjust the logical sector address and a host address pointer. The DMA context list manager also determines an instruction length based on a number of consecutive ones and issues one or more instructions for each group of consecutive ones and subtracts the instruction lengths from the overall transfer length until the transfer is complete.

Abstract: A method of improving a serial IO operation, where the serial IO operation includes at least one of a read operation of a data block and a write operation of a data block, and the serial IO operation is directed to a logical disk of a computerized data storage system. Only one stripe of data is read from the logical disk into a cache, and it is determined whether the data block for the IO operation is included within the cache. When the data block for the IO operation is included within the cache, then for a read operation, the IO operation is serviced from the cache. For a write operation, the cache is updated with the data block to be written, and only an updated parity block is written to the logical disk. When the data block for the IO operation is not included within the cache, then for a read operation, only one new stripe of data that includes the data block is read from the logical disk into the cache, and the IO operation is serviced from the cache.

Abstract: A memory management unit (MMU) for a device controller that provides enhanced functionality while maintaining a small physical size or footprint, such that the die size required to manufacture the memory management unit circuitry within the device controller integrated circuit device remains small notwithstanding such enhanced functionality. This compact/tiny MMU provides virtual memory addressing and memory error detection functionality while maintaining a small physical die size. The small physical die size with enhanced functionality is obtained by improvements in translating virtual to physical addressing without use of extensive translation tables, which themselves would otherwise consume memory and associated die real estate. In addition, the MMU allows a firmware image containing code and data segments to be run-time swapped between internal shared context RAM and external memory.
