Abstract:
A method of initializing a central processing unit (CPU) to run emulation code provided by a debugger, comprising the steps of:providing the central processing unit (CPU) in an unknown state;providing emulation logic for controlling an initialization sequence, said emulation logic being in communication with said CPU and said debugger;placing said emulation logic in a reset mode, such that no requests from said CPU or from said debugger are serviced;requesting said emulation logic to enter a start-up mode, in which only requests from said debugger are serviced;releasing said emulation logic from said reset mode, such that said emulation logic enters said start-up mode;placing said CPU in a desired initialization state; andreleasing said emulation logic from said start-up mode, such that said emulation code may be executed.
