Abstract
Design techniques and their circuit designs for versatile and scalable video coding 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 is partitioned into several sub-expressions. Taking each order of the add-and-shift series as a clock period, several adders/subtractors and a shift accumulator are used to carry out corresponding additions/subtractions and shift operations to finish the inner product operations. The calculating result is accumulated until all the orders are finished. The final accumulated value is the output of the transform coding. Data throughput rate can thus be enhanced to save the power consumption of the circuit system. Moreover, a dynamic guarded computation method and a switching power suppression technique are provided to further lower the power consumption.
