摘要： A method and system for allowing flexible control of access to a shared memory by multiple requesters. In a preferred embodiment, the invention arbitrates access to flash memory on a HBA between multiple host channels and HBA microprocessors, and eliminates contention possibilities for the flash during write cycles by the allowing a grant to be locked for a period defined by the flash write protocol and timing.

摘要： A method and system for allowing a host device (e.g., server) to perform programmed direct accesses to peripheral memory (e.g., flash) located on a peripheral device (e.g., HBA), without the assistance of a microprocessor located on the peripheral device. In a preferred embodiment, new host registers are implemented within controller circuitry of the peripheral device, the host registers being configured to be recognized by host software executed by host. The host device reads and writes to the host registers, which causes appropriate controller hardware to access the peripheral nonvolatile memory accordingly. By creating and implementing the new host registers, an enhanced controller is created that allows a host device to directly access peripheral memory, without peripheral processor assistance.

摘要： Re-sequencing commands and data between a master and slave device utilizing parallel processing is disclosed. When utilizing parallel processing while reading and writing data, there is a chance that the data will be read or written in an improper order, given the time delays associated with different slave devices and the processing time associated with various commands. Therefore, to retain the speed and improved performance of parallel processing while maintaining data coherency, the instructions and data are re-sequenced and processed in the proper order, and the returned data are re-sequenced and returned to the processor in the proper order.

摘要： Embodiments of the present invention are directed to a scheme in which information as to the future behavior of particular software is used in order to optimize cache management and reduce cache pollution. Accordingly, a certain type of data can be defined as “short life data” by using knowledge of the expected behavior of particular software. Short life data can be a type of data which, according to the ordinary expected operation of the software, is not expected to be used by the software often in the future. Data blocks which are to be stored in the cache can be examined to determine if they are short life data blocks. If the data blocks are in fact short life data blocks they can be stored only in a particular short life area of the cache.
