A 1.2 W 2.16 GOPS/720 MFLOPS embedded superscalar microprocessor for multimedia applications

A microprocessor with single instruction multiple data stream (SIMD) architecture and as many as 170 media instructions for multimedia embedded systems meets all requirements of embedded systems, including (a) MPEG2 (MP@ML) decoding and 3DCG image processing capabilities, (b) programming flexibility, and (c) low power dissipation and low cost. It also works as a general purpose microprocessor with mid-range performance. The microprocessor uses 0.21 /spl mu/m CMOS technology, and the chip achieves 2.16 GOPS/720 MFLOPS at a 180 MHz operation with 1.2 W dissipation.
