• abstract: A transpose switch matrix memory (TSMM) is proposed to enable a highly parallel single-chip CMOS sensor/image processor, Xetal, developed at Philips to perform JPEG compression at video rate (30 frames per second, fps) at an image dimension of 640/spl times/480 pixels. The integrated solution consists of 320 processing elements and 80 TSMMs, operates at 16 MHz clock rate and 3.3 V supply voltage, and is designed for fabrication at 0.25 micron technology. The processing system can sustain a maximum throughput of 5.12 billion operations per second consuming an estimated 120 mW providing a processing power efficiency of 7 BOPS/Watt. The Xetal architecture is capable of performing pixel level image processing such as fixed pattern noise (FPN) correction, defective pixel concealment, Bayer pattern filtering, RGB-YUV conversion, auto white balancing, and auto exposure control. The TSMM expands support to block level operations including chrominance subsampling, separable 8/spl times/8 recursive DCT, and ZZ scan required for JPEG.
