Scalable spatio-temporal parallel parameterizable stream-based JPEG-LS encoder

抄録

A parallel parameterizable stream-based JPEG-LS encoder architecture for scalable throughput is presented. The main contribution is the reconfigurable spatio-temporal parallelism to meet different pixel rates for lossless video compression, achieving the required throughputs with lower processing frequencies, scaled by the degree of spatial parallelism. The proposal allows for optimized performance associated to device resources and processing frequency. Experimental results were verified in Altera Stratix I FPGA device.
