COMPUTER SYSTEM PROVIDED WITH TRIGGER CONTROL INTERFACE AND METHOD

摘要

PROBLEM TO BE SOLVED: To unnecessitate the accurate timing of an arriving trigger signal and to operate more efficiently by making an interface temporarily store a trigger signal and to arbitrarily decide the order of data transfer. SOLUTION: An interface has a pointer register 160 which has a movable pointer 165 to a queue Q of a memory and a controller 170 which transmits a queue in either direction between the memory and a communication path 106 when a 1st trigger signal arrives by continuously receiving and accumulating a trigger signal T (i) and sending a start signal S (i) to the register 160. And, the controller 170 further receives a trigger signal while the queue is transmitted and when the transmission of the 1st queue is finished, it sends a start signal and further performs transmission. Here a buffer 175 of the controller 170 consists of priority order mechanisms and the buffer 175 offers the signal S (i) in the order of priority.
