Abstract: A codec (encoder-decoder) design for interfacing variable-length and fixed-length data compression is proposed in this paper. The advantage of variable-length codecs is known to have a high compression rate. The proposed codec converts the variable-length words into fixed-length packets, which can be hardwaredly and parallelly processed periodically, while keeping the high compression rate. In this work, additional symbols are encoded in the redundant padding bits of the fixed-length packets. This novel encoding scheme relaxes the intrinsic poor bit rate of the traditional fixed-length data compression. Physical measurements on silicon show that the bit rate is 900 Mbps to 1.5 Gbps given a 100 MHz system clock, which meets the 5 Kbps to 1.0 Gbps requirement of MPEG4.
