Abstract
PURPOSE:To shorten a program developing period by fetching input terminal data in a pattern memory into the input terminal of a CPU at the time of executing an input instruction and writing output data into a data memory at the time of executing an output instruction. CONSTITUTION:Input terminal data to the input terminal of an emulation CPU 1 can be stored into a pattern memory 3, and the data are written into respective input and output instruction deciding circuits 5 and 6 through a system address bus 9 and a data bus 10 of a host CPU. At the time of executing the output instruction, the output data of the CPU 1 are written into a data memory 4 with the circuit 6.
