Abstract :
A new algorithm and an adapted hardware architecture of an ASIP are proposed in this paper. When compared with other hardware ASIP implementations, this architecture significantly speeds up the motion estimation procedure and substantially decreases the memory requirements. Moreover, it also makes use of significantly fewer memory accesses, still maintaining its coding quality performances in what concerns both the obtained bit rate and PSNR. As a consequence, the proposed algorithm proves to be specially adequate to be implemented in most embedded systems with restricted computational and power resources that are often adopted by portable and battery supplied devices.
