Abstract

PURPOSE: To unify an expression of an address to a logical address display and to observe, etc., information obtained by an emulator, by the logical address display, by providing a means for converting a physical address on a bus, to a logical address.
CONSTITUTION: A given physical address P is checked by using adders 103W109, comparators 101, 111W117, and AND gates 119, 121. Subsequently, based on its result, by a logical address computer 123, the corresponding logical address L is obtained by using the physical address P and the contents bs1, bs2 of a base register. Also, the content (base address) BASE of the base register which has been used for generating its physical address are also outputted. Next, by comparing the address L with a logical address which has been stored in an emulator or a register in a host, an instruction is executed and an address of load/store of a data is monitored and various debugs can be executed. That is, an expression format of the address can be unified to a logical address display, and the debug work efficiency can be improved.
