Video-processing chip, audio-video system and related method capable of saving power

摘要

A video-processing chip capable of saving power is disclosed. The video-processing chip includes a microprocessor, a scalar, a first memory, and a second memory. The microprocessor is used for executing program codes. The scalar is used for adjusting a size of a received image. The first memory is coupled to the microprocessor and to the scalar for providing memory space to the scalar for image processing. The second memory is coupled to the microprocessor for storing the program codes of the microprocessor for controlling a power switch. Wherein a size of the first memory is greater than a size of the second memory.
