ABSTRACT:
A programmable controller includes a microprogram memory for holding a microinstruction, a code memory for holding each operation instruction for executing an operation as one word of instruction words having the same bit length, a data memory for holding the operation data, and an integrated central processing unit for executing the operation on the basis of the instructions from the code and data memories. The central processing unit includes a sequencer, a decoder, a program counter circuit, an instruction register circuit, a data memory control circuit, an address matching circuit, a control register circuit, a bit operation circuit, a register circuit, a fixed-point operation circuit, a floating-point operation circuit, and a multiplier circuit.
