DEVICE FOR PREVENTING PROCESS COLLISION BASED ON MULTIPLE INPUT SIGNALS

摘要

PROBLEM TO BE SOLVED: To provide a device for preventing process collision based on multiple asynchronous input signals by conducting a first come first serve process for multiple input signals being applied in an asynchronous manner so that no collision is generated and element operations having high reliability are realized.

SOLUTION: The device includes a signal input means 100 which receives a first input signal WR and a second input signal SR and generates first and second process request signals WR_STD and SR_STD, a collision control means 200 which controls the process collision in accordance with a predetermined priority and a signal processing section 300 which outputs a first process signal WRS in response to the first process request signal WR_STD and outputs a second process signal LDS in response to the second process request signal SR_STD.
