Cost-efficient 130nm TSMC forward transform and quantization for H. 264/AVC encoders

Abstract

Abstract—In this paper, we present a low cost Forward Transform and Quantization (FTQ) implementation for H. 264/AVC encoders in mobile applications. To reduce the hardware implementation overhead, the proposed design uses only one unified architecture of 1-D transform engine to perform all required transform processes, including discrete cosine transform and Walsh Hadamard transform. This design also enables to share the common parts among multipliers that have the same multiplicands. The performance of the design ...
