Abstract

PURPOSE:To perform flexible debug information processing, by converting a debug execution address besides an instruction address and an operand address to an actual by an address conversion mechanism to access a memory for debug, etc. CONSTITUTION:For the purpose of obtaining an actual address from a logical address for one virtual space, contents of a segment base register SBR and the S field of a logical address register LAR are inputted to an operator ALUO to obtain a pertinent address of a segment table ST, and this address is accessed to input a page table leading address PTC and the P field of the logical addres regiser LAR to an operator ALU1, and a pertinent address of a page table, and this address is accessed to read out an actual page address BPA. The virtual space is extended, and a debug information address space is provided, thereby performing flexible debug information processing.
