ABSTRACT:
The present invention improves a digital signal processor, more particularly, calculation methods for motion compensation in reducing a required amount of calculations when an amount of distortion between a last frame block and a current frame block; in processing a direct memory access at a higher efficiency; in processing a subdivided data calculation at a higher speed; in processing a branch instruction occurring in the pipeline process at a higher efficiency; and in processing an interruption occurring in a repeat process operation at greater convenience, and furthermore in reducing a required amount of calculations through minimum distortion searching processes hierarchized.
