Development of a real-time motion image encoder using codesign methodology

A real-time image encoder is designed by using codesign methodology is presented. The real-time image encoder composed of several functional modules. Each of these modules have their separate functions and can be built by software or hardware. Since there are so many combinations of hardware/software partitions can be found within these four modules. Thus, a good design methodology must be used to find a good hardware/software partition between these modules. In this paper, we use codesign methodology to partition the hardware and software of the real-time image encoder. Four major representative methods are chosen for discussion and performance evaluation. The results show that the codesign methodology can help us to select a good partition design and give up some designs that are not possible to meet the system specifications. Thus, it can shorten the design cycle and the development cost can be reduced.
