摘要： A memory access method for accessing data from a non-volatile memory in a south bridge is provided. Memory access is performed under a system management mode (SMM). Under the protection of the SMM mode, the desired memory address is not altered by an interrupt handler, therefore memory data is accessed correctly.

摘要： Apparatus and methods of adjusting system efficiency for a current-consuming system are disclosed. In the disclosed apparatus, a system current detector receives a system current from the current-consuming system and calculates a system current variation accordingly. A system efficiency adjustment module is coupled to the system current detector to receive the system current variation and output a frequency control signal and a voltage control signal accordingly.

摘要： A bus cycle trapping system includes at least one register, a north bridge, a south bridge and a central processing unit (CPU). The register is configured to store at least one trapping parameter. The north bridge traps a bus cycle matching the at least one trapping parameter while issuing an activating signal. The south bridge sends a system management interrupt message according to the activating signal. The CPU enters a system management mode according to the system management interrupt and executes a system management interrupt routine for doing a debugging test of the bus cycle matching the trapping parameter.
