PROGRAMMABLE ASSEMBLY LOGIC

PURPOSE:To facilitate the design of a wire logic by allocating a switch of a single section for each step of a software program and performing a wiring in response to a due instruction. CONSTITUTION:A shift switch 4 is divided into sections 1-n. The switches prepared within each section can perform the program functions with the connection secured among buses and a constant generating part 5 in accordance with the steps of a software program. Then a mask pattern for connection of these switches is produced in the final process for production of an integrated circuit. Thus it is possible to easily produce an element which has the function of the software program given through a wiring.
