Zusammenfassung: | The invention discloses a solid state disk read-write request parallel processing method. The system is composed of an address mapping module, a channel allocation module, a channel queue module, a to-be-processed queue module, a data buffer area and a garbage collection module. In the preprocessing process, for a read-write request, calculating a corresponding read-write channel, and then sendingthe read-write channel to a read-write queue corresponding to the channel; in the flash memory access process, parallel scheduling is carried out from the read-write queues of all the channels according to the request arrival sequence; for garbage collection, an active and passive combined mode is adopted, so that the influence of garbage collection on the read-write performance of the solid state disk is reduced. According to the method, a channel-level parallel structure in the solid state disk is utilized, pages are taken as units, and maximum parallel of data writing and reading is realized through reasonable sch |
