Abstract

Presented is a two-dimensional 8×8 discrete cosine transform (DCT) core processor for portable multimedia equipment with HDTV resolution in a 0.3μm CMOS triple-well double-metal technology which operates at 150MHz from a 0.9V power supply and consumes 10mW, only 2% power dissipation of a previous 3.3V DCT. Circuit techniques for dynamically varying threshold voltage reduce active power dissipation with negligible overhead in speed standby power and chip area.
