DEBUGGER APPARATUS AND DEBUGGING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce costs by miniaturizing a built-in emulation memory as much as possible in a debugger apparatus of a system LSI to which an ICE (in-circuit emulator) is not used and which operates at high speed.

SOLUTION: A host PC 102 is a computer loaded with debugger software. Writing to the built-in emulation memory with small capacity is efficiently performed, and overhead resulting from transfer traffic is prevented and the instructions are efficiently supplied to a CPU by preliminarily tracing instructions in an instruction executing order by the host PC 102, and transferring and storing the instructions in emulation memories 115, 116.
