A custom GZIP decoder for DTV application
Ke Zhu, Weidong Liu, Jiang Du · 2013
In this paper, we present a custom GZIP decoder for DTV application. Not only could GZIP decoder decompress the normal GZIP stream, but it also speed up the decompression for DTV application. The architecture exploits the principles of pipelining to the maximum extent in order to obtain high speed and throughput. A partial decoding approach is proposed to deal with the decompression with the limited memory. The decoder has been implemented with Verilog HDL and then synthesize the design with TSMC 55nm (GP) technology. The proposed design exhibits an operation frequency of 300MHz and costs about 233K equivalent gates. The throughput of our design is about 95MB/s.
