PURPOSE:To realize fast, high-precision arithmetic through small-sized constitution by constituting one arithmetic device by using three LSI chips for signal arithmetic, memory address arithmetic, and input/output operation. CONSTITUTION:For example, when repetitive arithmetic is performed, the memory address arithmetic chip 1 increases the address by one every time when the arithmetic is performed once. When one instruction is executed and the memory address arithmetic is completed, the chip 11 sends a program memory-up signal to a program memory part 1 through an OR circuit gate 14 to advance a program by one. A memory part 3 reads and writes a signal by the chip 11. The arithmetic chip 12 processes the signal from the memory part 3 by an instruction from the memory 1 and stores the result in the memory part 3. Further, the input/output chip 13 performs signal input and output between the outside and memory part 3 when an input and an output instruction are read out of the memory part 1. |
