Data storewidth accelerator

摘要

A data storage controller (20) employing lossless or lossy data compression and decompression to provide accelerated data storage and retrieval bandwidth. In one aspect, a data storage controller comprises a digital signal processor (DSP) (21) comprising a data compression engine (DCE) for compressing data stored to the data storage device and for decompressing data retrieved from the data storage device; a programmable logic device (22), wherein the programmable logic device is programmed by the digital signal processor to instantiate a first interface (14) for operatively interfacing the data storage controller to the data storage device and to instantiate a second interface (15) for operatively interfacing the data storage controller to a host; and a non-volatile memory device (24), for storing logic code associated with the DSP (21), the first interface (14) and the second interface (15). The data storage controller further comprises a cache memory device (23) for temporarily storing data that is processed by or transmitted through the data storage controller (20).
