Abstract: PURPOSE: To provide a controller in which design of a new controller by every change of a data processing method is unnecessitated and which is designed not to depend on internal data processing ability very much. CONSTITUTION: An intermediate data processing of a digital signal outside an integrated circuit is selectively made possible by a system 10 and a transcoder 101, a codec 102 connected to the transcoder 101 and a data processor located outside time IC are included in the system 10. The digital signal is switched between the transcoder 101 and the codec 102 by responding to a strobe signal and transmitted to a data route of an external processor by a programmable switch. The digital signal is formatted in the IC and processed by the external processor. The digital signal which is processed outside is returned from the external processor to the IC with the data route. After that, the digital signal is formatted again in the IC and further processed by the IC.
