`
`ABSTRACT
`
`Systems and methods for providing accelerated data storage
`and retrieval utilizing lossless and/or lossy data compression
`and decompression. A data storage accelerator includes one
`or a plurality of high speed data compression encoders that
`are configured to simultaneously or sequentially losslessly or
`lossy compress data at a rate equivalent to or faster than the
`transmission rate of an input data stream. The compressed
`data is subsequently stored in a target memory or other stor(cid:173)
`age device whose input data storage bandwidth is lower than
`the original input data stream bandwidth. Similarly, a data
`retrieval accelerator includes one or a plurality of high speed
`data decompression decoders that are configured to simulta(cid:173)
`neously or sequentially losslessly or lossy decompress data at
`a rate equivalent to or faster than the input data stream from
`the target memory or storage device. The decompressed data
`is then output at rate data that is greater than the output rate
`from the target memory or data storage device. The data
`storage and retrieval accelerator method and system may
`employed:
`in a disk storage adapter to reduce the time
`required to store and retrieve data from computer to disk; in
`conjunction with random access memory to reduce the time
`required
`to store and retrieve data from random access
`memory; in a display controller to reduce the time required to
`send display data to the display controller or processor; and/
`or in an input/output controller to reduce the time required to
`store, retrieve, or transmit data.
