| Abstract: | With the perspective of increasing the degree of parallelism of the on-chip peripherals and the core, this paper introduces the pipeline idea, implements a control architecture based on polling and ping-pong buffers, and develops it to an improved dual-stage control architecture. H.264-based video encoder is implemented under the architecture. Practical tests show that this system can meet the requirements of real-time capability and stability in video communications. |
