PURPOSE:To make main and service processors read and write data targeting all FFs, to enable the service processor to conduct it simultaneously, and to enable communications between both processors by providing an address decoder, a conciliation means, and a switching means. CONSTITUTION:Data can be written into and read out of not only a FF 16, but also all the FFs 16 included in all hardwares from a main processor 1 through the process of detecting 4, 5 accesses, conciliating.switching 6, 7 access requests, and selecting 12-15 processors. Similarly, data can be written into and read out of the FF 16 not only through a scanning circuit, but also in synchronism with the processor 1 from the service processor 2. Since both processors can written into and read out of mutual data the FF 16 in tuning, communications between both can be conducted securely without using the interruption between the processors. |
