An exploration on hardware/software co-design H.264 decoder
نویسندگان
چکیده
For the H.264/MPEG-4 AVC, there are purely hardware codec and solely software solutions. They are known to have either the best performance in terms of energy and speed or the flexibility. This project aims at examine the possible partitions between HW/SW and evaluate its tradeoffs between the flexibility and performance. Keywords-H.264, bitstream, deblocking filter

Hardware and Software Co-design Issues in H.264 Decoder
In this paper we talk about mixed architectures of a H.264/AVC video decoder. Here software part of decoder was implemented in NIOS II processor on a FPGA prototyping board (Stratix III). Software and hardware architectures was proposed to increase the decoder output performance. Based upon the time execution parameters, data dependency constraints, the decoder partitioning is applied. Here the...

Existing hardware software (HW-SW) co-design methodologies mainly focus on HW-SW co-simulation to build a virtual prototyping environment that enables software design and system verification without need of making a hardware prototype. However, it fails to reduce the gape between design productivity and system complexity. It is required to target additional design problems such as design space ...

Reducing the product development cycle time is one of the most important and challenging problems faced by the industry today. As the functionality and complexity of devices increases, so does the time required to design, test, and develop the devices. Developing products rapidly in the face of this increasing complexity requires new methodologies and tools. This paper presents a methodology fo...
متن کاملA Platform-Based MPEG-4 Advanced Video Coding (AVC) Decoder with Block Level Pipelining
We present a baseline MPEG-4 AVC (Advanced Video Coding) decoder based on an optimized platform-based design methodology. With this methodology, we jointly optimize the software and hardware design of the decoder. Overall decoding throughput is increased by synchronizing the software and the dedicated co-processors. The synchronization is achieved at macroblock-level pipelining. In addition, we...
