An Architecture for Programmable Multi-core IP Accelerated Platform with an Advanced Application of H.264 Codec Implementation

Abstract

A new integrated programmable platform architecture is presented, with the support of multiple accelerators and extensible processing cores. An advanced application for this architecture is to facilitate the implementation of H.264 baseline profile video codec. The platform architecture employs the novel concept of virtual socket and optimized memory access to increase the efficiency for video encoding. The proposed architecture is mapped on an integrated FPGA device, Annapolis WildCard-II™ or WildCard-4™, for verification. According to the evaluation under different configurations, the results show that the overall performance of the architecture, with the integrated accelerators, can sufficiently meet the real-time encoding requirement for H.264 BP at basic levels, and achieve about 2–5.5 and 1–3 dB improvement, in terms of PSNR, as compared with MPEG-2 MP and MPEG-4 SP, respectively. The architecture is highly extensible, and thus can be utilized to benefit the development of multi-standard video codec beyond the description in this paper.

A Prototyping Virtual Socket System-On-Platform Architecture with a Novel ACQPPS Motion Estimator for H.264 Video Encoding Applications

Abstract

H.264 delivers the streaming video in high quality for various applications. The coding tools involved in H.264, however, make its video codec implementation very complicated, raising the need for algorithm optimization, and hardware acceleration. In this paper, a novel adaptive crossed quarter polar pattern search (ACQPPS) algorithm is proposed to realize an enhanced inter prediction for H.264. Moreover, an efficient prototyping system-on-platform architecture is also presented, which can be utilized for a realization of H.264 baseline profile encoder with the support of integrated ACQPPS motion estimator and related video IP accelerators. The implementation results show that ACQPPS motion estimator can achieve very high estimated image quality comparable to that from the full search method, in terms of peak signal-to-noise ratio (PSNR), while keeping the complexity at an extremely low level. With the integrated IP accelerators and optimized techniques, the proposed system-on-platform architecture sufficiently supports the H.264 real-time encoding with the low cost.
