81MS/s JPEG2000 single-chip encoder with rate-distortion optimization
An 81MS/s JPEG 2000 single-chip encoder is implemented on a 5.5mm/sup 2/ die using 0.25/spl mu/m CMOS technology. This IC can encode HDTV 720p resolution at 30 frames/s in real time. The rate-distortion optimized chip encodes tile size of 128/spl times/128, code block size of 64/spl times/64, and image size up to 32K/spl times/32K.
