Low Cost and High Performance Implementation of Forward Transform and Quantization for an H. 264/AVC Encoder

Abstract

Abstract—This paper presents a low-cost and highperformance hardware design of forward transform and quantization (FTQ) for an H. 264/AVC encoder. To minimize the hardware imple-mentation cost, in this design we use only one unified architecture of 1D transform engine to perform all transform processes. While the performance of the design is improved by using a fast architecture of the multiplier in the quantizer. Furthermore, this architecture also enables to share the common part among multipliers that have the same multiplicand ...
