ABSTRACT:
The described embodiments include a system for performing data compression. The system includes a compression mechanism with N channels, and an internal decompression mechanism in the compression mechanism that accepts N channels of fixed-length packets. The compression mechanism is configured to receive an input bit stream that includes a set of data words. In response to receiving a request from the internal decompression mechanism identifying at least one of the channels for which a fixed-length packet is to be appended to the output stream, the system fills a fixed-length packet for the identified channel with compressed data words; appends the fixed-length packet to the output stream; and forwards a copy of the fixed-length packet to the internal decompression mechanism. The internal decompression mechanism decompresses fixed-length packets for each of the channels to determine a next fixed-length packet to be appended to the output stream.
