Title:
SEQUENCE CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS59189407
Kind Code:
A
Abstract:
PURPOSE:To raise the use efficiency of a memory for storing a program by suppressing an increase of a processing time caused by shifting a program to a program storage part from a temporary storage part of the program. CONSTITUTION:Data from an external process is inputted to an operation controlling circuit 2 through an inputting circuit 1, and anecessary operation processing is executed. A program executed by this operation controlling circuit 2 is executed by a storage part 4 consisting of change address registers 8, 9 for storing temporarily a jump instruction for making access to a part of a changed program, and a program storage part 6. In this case, the jump instruction is set to the change registers 8, 9, and the changed program can be accessed easily. Also, the changed program is stored successively after the program generated and stored in the beginning, so as to jump to some changed program by the jump instruction as necessary, it becomes unnecessary to divide the program storage part into blocks, and the memory is used efficiently.
