Abstract
PURPOSE:To realize the high efficiency for the processing of information, by performing the execution an interchangeable and extended instruction word with a conventional software the instruction word level and in a speed equal to a conventional instruction word with the reduced hardware quantity. CONSTITUTION:An instruction is held at a register 21, and the address information CSR is read through an auxiliary control storage device 22 to be held at a CSR register 23. In case the instruction word corresponds to the conventional software, an identification code SWADR is logic (0) and the instruction word corresponds to a new software; while the code SWADR is logic (1) with an extension instruction. In the case of SWADR = 1, the link information between a part of a start address CSRA and the extended part of an instruction code OP is delivered to a control storage device 26 in the form of a start address CSSA0-13. A gate circuit 25 delivers the address CSSA0-13 to the device 26 by a start signal FFSTART. The instruction is held at a microinstruction register 27, and the extension instruction is executed.
