<p>PROBLEM TO BE SOLVED: To attain high speed lock processing by using a memory mapped communication register without changing any processor in a multi-processor system. SOLUTION: This multi-processor system is provided with communication register modules 400-402 corresponding to processors 10-12 one to one, and a lock processing test operation is operated to the corresponding communication register modules, and a lock value set operation and an unlock operation are operated through an inter-communication module bus to all the communication modules by executing simultaneous writing control.</p> |
