Realization of H.264 Video Encoder of Real-time HD Based on Dual-DSP

The realization of high definition(HD) video based on H.264 compression standard requires high performance of hardware.In this paper,a dual-DSP processing scheme is proposed.The problem of parallel,coordination and communication between two DSPs are discussed in detail,and the corresponding solutions are put forward.TI TMS320C6455 DSP which supports C64x + core is utilized.Serial RapidIO(SRIO) interface is adopted to transfer data between DSPs.Experimental results show that the processing time of HD 720p is in 40 ms which meets the real-time processing for HD video requirements.
