Xetal-II: A 107 GOPS, 600 mW Massively Parallel Processor for Video Scene Analysis

Xetal-II is a single-instruction multiple-data (SIMD) processor with 320 processing elements. It delivers a peak performance of 107 GOPS on 16-bit data while dissipating 600 mW. A 10 Mbit on-chip memory is provided which can store up to four VGA frames, allowing efficient implementation of frame-iterative algorithms. A massively parallel interconnect provides an internal bandwidth of more than 1.3 Tbit/s to sustain the peak performance. The IC is realized in 90 nm CMOS and takes up 74 mm
