摘要：Design techniques and their circuit designs for versatile and scalable videocoding are proposed, in which the inner product operation in the transform coding

expression is taken apart into a series of add and shift operations, and the expression ispartitioned into several sub-expressions. Taking each order of the add-and-shift series asa clock period, several adders/subtractors and a shift accumulator are used to carry outcorresponding additions/subtractions and shift operations to finish the inner productoperations. The calculating result is accumulated until all the orders are finished. Thefinal accumulated value is the output of the transform coding. Data throughput rate canthus be enhanced to save the power consumption of the circuit system. Moreover, adynamic guarded computation method and a switching power suppression technique areprovided to further lower the power consumption.
