This paper presents a VLSI implementation of the lossless block-based predictive Rice codec (BPRC). The BPRC uses an adaptive predictive coding algorithm to remove the redundancy in the image, codes the residue using an entropy coder. This algorithm can adapt well to local images statistics. The codec chip will encode 4 to 16-bit pixels at 10 Mpixels/sec input, and decode at 10 Mpixels/sec output. For images of normal size it requires little supports circuitry, only input data formatting and output data defomatting. Large images can be supported with external FIFOs.
