ABSTRACT:
A method for blocking a request to a front side bus interconnected between a central processing unit (CPU) and a control chip includes the following steps. First, a bus ownership of the control chip is assigned via a bus priority signal line. Any request from the CPU to the front side bus is blocked when the control chip owns the bus ownership. Meanwhile, any request from the control chip to the front side bus is inhibited when the CPU is blocked from outputting any request to the front side bus.
