Abstract
A computer system embodies a first hardware (X) architecture for providing an X domain for an X code. The computer system includes a system for simulating a second hardware (Y) architecture providing a Y domain for Y code and for executing the Y code, and a debugger operable in the Y domain for debugging the X and Y codes. The simulating system includes a sub-system for providing support services for the debugger to enable it to debug the Y code, including modification of Y machine state and setting of breakpoints. The computer system also includes a sub-system for generating a call for cross-domain memory data access under predetermined conditions, such as direct memory access failures.
