发明名称 Direct memory access from host without processor intervention
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.
