MULTIPROCESSOR CONTROL SYSTEM, BOOTING DEVICE AND BOOTING CONTROLLER USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To shorten the activation time and changeover time of an application by integrally controlling access to a common bus line and performing high speed booting while reducing processor peripheral circuits relating to booting in multiprocessor constitution for loading plural processors on the same board. ;SOLUTION: The booting request of the respective processors 311-313 is transmitted to a time sharing control part 33 by a processor status control part 35 and a polling control part 36. Then, the time sharing control part 33 generates a time slot for performing booting, reads required booting data from a storage device 42 storing the booting data by using the time slot and supplies them through the common bus line 30 to the respective processors 311-313 of a processor part 31.;COPYRIGHT: (C)1999,JPO
