PURPOSE:To always perform an operation with suited internal constitution and to increase the processing speed, by varying the connection among one or plural registers, an arithmetic unit and a data bus based on a program instruction. CONSTITUTION:The signal of a signal line 10 which indicates the connection at a connection controlling part is decoded by a decoder 41 by an instruction of a program. The value of output signals 301-436 are set at 0 or 1. This output signal line controls the intersections 101-236 among the input signals lines 8- 31 and the output signal lines 8-24 of a data bus, an arithmetic unit and a register. In such constitution, the combination among the register, arithmetic unit and data bus can be varied in various ways for each desired operation. |
