A single-chip MPEG2 MP@ML video encoder LSI integrates 81MOPS controller and motion estimator using two adaptive algorithms (maximum search area of ˜288 horizontal and ˜96 vertical pixels) reduces computation to 0.5% of full search. The 13.7x12.4mm2 4.5M-transistor device in 0.4um CMOS dissipates 1.2W at 3.3V.

A 12M-transisor 9x9mm2 MPEG4 video codec in a 0.3um CMOS triple-metal technology uses 3.3V, 2.5V, and 1.75V power supply voltages generated from an external 3.3V power supply and consumes 60mW at 30MHz. Variable VDD and Vth, clustered voltage scaling, level-shift flip-flop, conditional clocking, and local memory architecture reduce power dissipation by 70%, compared to that of a conventional design.

A 0.5um 130mm2 1.8M-transistor CMOS IC integrates a 8k-FFT in 400ns for OFDM demodulation for digital terrestrial TV based on the DVB-T standard. A 140mm2 4.5M-transistor IC performs channel estimation/correction. These ICs are included in a global chipset receiver (specified in the DVBird European project) with channel decoder and synchronization ICs.
