In order to implement the real-time video compression system, the compression algorithm should be improved and also need a reasonable control framework which brings no additional overhead and efficient to use of the hardware resources. With the perspective of improve the degree of parallelism of the on-chip peripherals and the core, this paper analyzed the disadvantages of the ping-pong buffers pipeline mechanism at first, and then introduced a improved control framework based on dual-core DSP polling control and ping-pong buffers pipeline to avoid that disadvantages. A H.264 based video encoder used this control framework was implemented on the platform of ADSP-BF561, and the experimental results show that the framework can meet the video compression systempsilas real-time capability and reliability requirements by reducing the coding time, falling the frame loss frequency and improving the system's work efficiency.
