DIGITAL SIGNAL PROCESSOR USING HANDSHAKE INTERFACE AND OPERATING METHOD THEREOF

摘要

A digital signal processor using handshake interface and a method of operating the digital signal processor are provided to vary application programs executable in the digital signal processor for improving extensibility, and change a power mode according to the operating state of the digital signal processor for reducing power consumption. A request signal for executing an application program is received from an external device(S11). An address corresponding to the request signal is read(S13). An application program code corresponding to the address is read from a program memory in which at least one application program code is recorded(S14). The requested application program is executed according to the read application program code(S15). A completion signal which represents that the execution of the application program is completed is output(S16).
