Abstract
A signal processing device includes an integrated processor, a video processing unit coding a video signal, and an interface controlling a bus ownership between the integrated processor and an external processor. The interface detects the integrated processor accessing an external device and asserts a bus request. Thus the signal processing device can process data with a shorter cycle and thus more efficiently.
