Decompression history buffer read/write pipelines

机译:解压缩历史记录缓冲区读/写管道

摘要

A method for a hardware decompression read pipeline, the method including determining a length and a distance of a first entity from a buffer; launching a first read request for reading a first data from the buffer; obtaining a second entity from the buffer; determining a distance of the second entity; calculating a new distance for the second entity; and decreasing a first counter by one for each cycle that data is read and returned from the buffer, wherein, when a first number of pending read data clock cycles in the first counter is less than a predetermined number of clock cycles and there is no read-after-write conflict: launching a second read request prior to completion of the first read request. In other aspects, a method for a hardware decompression write pipeline and systems for a hardware decompression read pipeline and a hardware decompression write pipeline are provided.
