Abstract :
In this work, a highly parallel and flexible framework based on a multicore processor which is especially optimized for computation-intensive execution is proposed to accelerate motion estimation for HEVC. Using multilevel on-chip communication mechanism greatly enhances efficiency and flexibility of data exchange in motion estimation. Experimental results not only validate the feasibility of the framework, but also show that ME achieves 8.5 times speedup comparing to typical frameworks while 16 cores are utilized.
