A low power VLSI implementation for JPEG2000 codec

This paper proposed a low power VLSI implementation of JPEG2000 codec. Three power optimization schemes including gated clock, bus-invert and dual voltage scaling are adopted. An automated design flow for dual voltage scaling is also proposed. The JPEG2000 codec was fabricated in SMIC 0.18/spl mu/m 1P6M standard CMOS technology. And it is capable of JPEG2000 compression/decompression with a 1280/spl times/1024 pixel (YUV422 full color) at 20frames/s employing a 100MHz operating frequency. The power consumption is reduced by 54% and is 465mW @ 1.8V and 100 MHz.
