Abstract

PURPOSE:To shorten data setting time and test processing time by setting simultaneously input data from the outside in a plural registers. CONSTITUTION:Instruction codes read from an ROM1 are divided, for example, to three blocks and are inputted to decoders 2-4. Outputs of these decoders 2-4 are sent to an execution unit part 18, programs assigned respectively with controlling signals are executed. On the other hand, data required for the processed result and the processing are introduced to or derived out of input-output terminals 6 through an internal bus 5. Further, registers 7-9 are connected in common to the bus 5 respectively and these are inputted via a switching circuit 10 into the decoders 2-4. Here, data input control to the registers 7-9 is performed independently or simultaneously by input controlling signals 15-17.
