Title: Runaway preventing method for transmission program of phase pulse signal
Inventor: ARAI YUKIO
IPC: G06F11/00
Filed: 1983-01-10
Abstract: PURPOSE:To execute a transmission program for phase pulse signal of the next cycle in a normal way through an arithmetic processor by resetting immediately an arithmetic device when a program has a runaway. CONSTITUTION:The reference pulse supplied from a reference pulse generating circuit 2 is impressed to the synchronizing input terminal 4 of the arithmetic processor CPU3, and therefore the CPU3 starts a transmission program for a phase pulse signal and ends one cycle of the program before the fall of the reference pulse. At the same time, the reference pulse is impressed to the input side of an ANd gate 10 of negative logic as well as to the reset input terminal R of a D flip-flop 9 via a differentiating circuit. When a program has a runaway, the potential of an output terminal 5 of the CPU3 is kept at a low level with the output of the gate 10 kept at a high level respectively. Thus a monostable multivibrator 11 is triggered. The output of the vibrator 11 is used as a reset signal of the CPU.
