28 fEEE Micro A fabricated, tested, fully functional40-MHz device perfonns the 8x8 inverse discrete cosine transform for digital HDlV decoders. It converts four I4-bit OCT coeffi cients into four ll-bit pixel values each cycle. Fixed-coefficient multiplier Walla ce trees (in which partial products are rounded before summation) help compute the inner products. The 3I,OOO-gate device was implemented in a 10.5-mm die using a I-micron CMOS array-based process.
