PROBLEM TO BE SOLVED: To provide an inter-DSP synchronizing method that shortens the time needed for synchronization among a plurality of DSPs and decreases the frequency of use of a common bus at the same time. SOLUTION: The inter-DSP synchronizing method of synchronizing the plurality of DSPs 11 to 13 connected to the common bus comprises a first step of processing input data input through the common bus by the first DSP 11, a second step of writing processing end data indicating that processing of the input data by the first DSP 11 is completed to an internal memory 12a of the second DSP 12 through the common bus 10, a third step of making the second DSP 12 detect the processing end data being written to its own internal memory 12a, and a fourth step of making the second DSP 12 process the processing data having been processed by the first DSP 11 after detecting the processing end data being written.
