CONTROL METHOD FOR ADDITIONAL PROCESSOR

摘要

PURPOSE:To produce and execute a executing program having no dependence on a memory mapped input/output address by providing an address register to position the memory addresses for input/output as the relative addresses. CONSTITUTION:A start address is decided by an address register 21 and a mapped input/output address 22 forms a compiler that delivers such an object that can be shown in a relative address through the register 21. Thus an access is possible to the address 22 of an additional processor through a relative address register. In such a way, it is possible to produce and execute an executing program with no dependence on a system where the size of a program executing a area varies such a program that refers directly to the address 22 in a real number arithmetic mode.
