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...
The elaboration of new and innovative systems such as MPSoC (Multiprocessor System on Chip) which are made up of multiple processors, memories and IPs lies on the designers to achieve a complex codesign work. Specific tools and methods are needed to cope with the increasing complexity of both algorithms and platforms. Our approach to design such systems is based on the usage of a high level of abstraction...
In this paper we focus on the design methodology to propose a design that is more flexible than ASIC solution and more efficient than the processor-based solution for H.264 video decoder. We explore the memory access bandwidth requirement and different software/hardware partitions so as to propose a configurable architecture adopting a DEM (Data Exchange Mechanism) controller to fit the best tradeoff...
In this paper, a decoding IP core for audio video coding standard (AVS) was designed, which can support AVS JiZhun profile High-Definition video bit stream real-time decoding. System composing of the SOC design and control flow of decoding was described in detail. Logical and feasible division between software and hardware was presented on the basis of sufficient validity check. C reference model...
