An embedded 4-channel real-time multimedia coding system

With the growing of multimedia applications, requirement for embedded multimedia systems becomes popular In this paper we design and implement an embedded 4-channel real-time video and audio coding system (VACS). To achieve real-time coding of 4-channel video and audio, we optimize the coding software at algorithm, system and code level. Experimental results of VACS indicate that it works efficiently. Furthermore, since the hardware framework of VACS is based on programmable devices (DSP and FPGA), consequently by realizing diverse multimedia processing algorithms, VACS can also satisfy the requirement of some other embedded multimedia applications
