    • 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 storage 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 simultaneously 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.
    • 利用无损和/或有损数据压缩和解压缩来提供加速数据存储和检索的系统和方法。 数据存储加速器包括一个或多个高速数据压缩编码器,其被配置为以等于或快于输入数据流的传输速率的速率同时或顺序地无损或有损压缩数据。 随后将压缩数据存储在其输入数据存储带宽低于原始输入数据流带宽的目标存储器或其他存储设备中。 类似地,数据检索加速器包括一个或多个高速数据解压缩解码器,其被配置为以等于或快于来自目标存储器或存储设备的输入数据流的速率同时或顺序地无损或有损地解压缩数据。 然后以比目标存储器或数据存储装置的输出速率大的速率数据输出解压缩数据。 数据存储和检索加速器方法和系统可以采用:在磁盘存储适配器中,以减少从计算机到磁盘存储和检索数据所需的时间; 结合随机存取存储器,以减少从随机存取存储器存储和检索数据所需的时间; 在显示控制器中减少将显示数据发送到显示控制器或处理器所需的时间; 和/或在输入/输出控制器中以减少存储,检索或发送数据所需的时间。

    • Systems and methods for providing fast and efficient data compression using a combination of content independent data compression and content dependent data compression. In one aspect, a method for compressing data comprises the steps of: analyzing a data block of an input data stream to identify a data type of the data block, the input data stream comprising a plurality of disparate data types; performing content dependent data compression on the data block, if the data type of the data block is identified; performing content independent data compression on the data block, if the data type of the data block is not identified.
    • 使用独立于内容的数据压缩和依赖于内容的数据压缩的组合来提供快速有效的数据压缩的系统和方法。 一方面,一种用于压缩数据的方法包括以下步骤:分析输入数据流的数据块以识别数据块的数据类型,所述输入数据流包括多个不同的数据类型; 如果数据块的数据类型被识别,则对数据块执行依赖于内容的数据压缩; 如果数据块的数据类型未被识别,则对数据块执行内容独立的数据压缩。
