The algorithm, patented by the way, is oriented to lossless compression of HIGH SPEED signals, "New data compression technologies can save power and cost in applications with sampling rates above 10 Msamples/sec." A lot above usual digital frequencies. See: http://www.dspdesignline.com/208808676;jsessionid=CEV13G2LQ4VWDQE1GHPSKHWATMY32JVN?pgno=1 Data compression for high-speed DSP, part 1 and http://www.embedded.com/columns/technicalinsights/209400089?_requestid=198348 Data compression for high-speed DSP, part 2 In Part 2 it is compared with LZ algorithms, of PKZIP fame. Somewhat better, around 50% better, probably at the same level of the algorithms already used for sound. It advantage, is efficient implementation, in power, instructions and pin count of DPS/FPGA chips, used for real time compression of those high-speed images. Also see, if interested: http://www.dsp-fpga.com/articles/id/?4458 Compressing ADCs defuses data rate explosion in Data Acquisition Systems There is some use for lossy compression, like ogg and mp3, but it not well explained in the article Final words of Part 2: "By integrating compression into high-speed signal processing systems, end-to-end system performance is maintained with reduced pin count, memory, power, and cost. Just as speech, audio, image, and video compression are now ubiquitous and integrated components of consumer media, we believe that compression for high-speed DSP systems will someday become as ubiquitous as these low-speed compression algorithms have become." -- A.
