Title: Queue control system
Inventor: SUZUKI HIROYUKI
IPC: G06F9/48
Filed: 1987-12-26
Abstract: PURPOSE:To shorten the processing time of an interruption routine by using a means which sets an unused queue after a working queue. CONSTITUTION:A single chain 23' is composed by setting an unused queue after a working queue. An event queue control table 24' has such a constitution that controls the head address of the working queue, the head address of the unused queue, and the address of the final queue. When a new event occurs, it is just required for an interruption routine 20' to write the necessary data at the head of the unused queue and to replace the head queue address contained in the table 24'. Thus the reconnection is omitted among queue blocks, that is, the replacement of the NEXT parts is not required. As a result, the chain 23' is never broken even though the routine 20' works during the working of an event information processing routine 22'.
