The coding tools involved in H.264 however make its video codec implementation very complicated raising the need for algorithm optimization and hardware acceleration. In this paper a novel adaptive crossed quarter polar pattern search ACQPPS algorithm is proposed to realize an enhanced inter prediction for H.264. Moreover an efficient prototyping system-on-platform architecture is also presented which can be utilized for a realization of H.264 baseline profile encoder with the support of integrated ACQPPS motion estimator and related video IP accelerators. The implementation results show that ACQPPS motion estimator can achieve very high estimated image quality comparable to that from the full search method in terms of peak signal-to-noise ratio PSNR while keeping the complexity at an extremely low level. With the integrated IP accelerators and optimized techniques the proposed system-on-platform architecture sufficiently supports the H.264 real-time encoding with the low cost. Copyright 2009 Y.
