Abstract

PURPOSE:To prevent the increase of an overhead or the complication of a program by transferring an instruction interpreted by a first processor to the program counter of a second processor. CONSTITUTION:The first processor 1 is provided with an instruction fetching circuit 11 and an instruction decoder 12 and further stores the output of the instruction decoder 12 in a data register 13. The second processor 2 stores the contents of the data register 13 of the first processor 1 in the program counter 21 and stores a program in a program memory 22 controlled by the program counter 21 in the same address as the first processor. Thereby, at the second processor 2, the interpretation of command is not required and an over head is shortened, as well and the program of the first processor can be simplified.
