PURPOSE:To re-write a microprogram or a coefficient at high speed without causing a hindrance to a DSP processing. CONSTITUTION:A coefficient utilizing means processes a digital signal operation corresponding to an algorithm stipulated by the microprogram through the use of the coefficient. A first and the second transfer buffer 1a and 1b temporarily store data for rewriting the microprogram and the coefficient inputted from an external processor so as to output restored data for rewriting to a microprogram storing means 32 and a coefficient storing means 34. Either of the first and second buffer 1a or 1b operates the storage of rewriting data and the other one operates the output of rewriting data. The storing operation and the output operation of the first and second buffer 1a and 1b are executed based on the operation clock of the coefficient utilizing means inside a digital signal processing processor. |
