This paper presents a novel hardware architecture for the real-time high-throughput implementation of the adaptive deblocking filtering process specified by the H.264/AVC video coding standard. A parallel filtering order of six units is proposed according to the H.264/AVC standard. With a parallel filtering order (fully compliant with H.264/AVC) and a dedicated data arrangement in local memory banks,...
The expansion of the market for embedded systems has motivated academic research to offer solutions to the problems of congestion and connectivity. Indeed, the implementation of the embedded processor on FPGA helps saving space and provides a better interaction between the program and hardware acceleration. Furthermore, the addition of an Operating System (OS) allows to abstract the hardware and to...
This paper describes an efficient hardware architecture for the deblocking filter used in H.264/AVC baseline profile video coding standard and optimized for real time implementation. Thus, the deblocking filter is a computationally and data intensive tool resulting in an increased execution time of both encoding and decoding processes. In fact, the processing order of the filter and the memory organization...
The H.264/AVC standard achieves much higher coding efficiency than previous video coding standards. Unfortunately mis comes with a cost in considerably increased complexity at the encoder mainly due to motion estimation. Therefore, various fast algorithms have been proposed for reducing computation but they do not consider how they can be effectively implemented by hardware. In this paper, we propose...
Motion estimation (ME) is one of the most time-consuming parts in video encoding system, and significantly affects the output quality of an encoded sequence. In this paper, we present hardware implementation of the Large Diamond Parallel search algorithm. This hardware is designed to be used as part of a complete H.264 video coding system. This architecture is simulated and tested using VHDL and synthesized...
