The off-chip memory bandwidth is often a critical part of a video processing system. Traditional cache usually behaves poor since some video algorithms, such as motion compensation, tend to access memory in an inefficient way. An efficient memory bandwidth architecture for video decoder is proposed in this paper. Two bandwidth optimization strategies are proposed through pixels reconstructed and data...
Multiprocessor-system-on-a-chip will be the dominating architecture in embedded systems as it provides an increase in concurrency improving the performance of the system rather than increasing the clock speed which affects the power consumption of the system. However, concurrency needs to be exploited in order to improve the system performance in the different applications'environments. The new emerging...
In this paper motion compensation IP core design based on SOPC technology is researched, which achieves the software hardware co-design method in video decoding to overcome the drawbacks of the software decoding and hardware decoding. The design of hardware modularization which is based on the motion compensation algorithm in MPEG-4 video decoding standard is completed by using verilog HDL language...
Computing-intensive algorithms which occupy most of executing time are always the main bottleneck in real-time or high quality video applications. In this paper, the optimization methods of the computing-intensive decoding algorithms of H.264, including MC (Motion Compensation), Deblocking and IDCT-IQ (Inverse Discrete Cosine Transform-Inverse Quantization), are proposed firstly, and then implemented...
