A Low power and highly parallel implementation of the H.264 8 × 8 transform and quantization

Abstract

With the appearance of new video standards like H.264/AVC, demands of real-time encoding are increasing. Real-time is a main necessity for video compression and transmission. Discrete Cosine Transform (DCT) and quantization in H.264 have an important role to express real-time. Nevertheless, for real time operation, parallel processing is the most powerful approach that can be used to give considerable compression performance at standard definition (SD) and high definition (HD) resolution. In this paper a highly parallel hardware implementation of the H.264 8×8 integer transformation and quantization is presented. Experiment results show that this architecture satisfies the real-time constraints intended by different video mobile application.
