This invention relates to a debug device and method thereof and is applied to detect transmission on a bus in a computer system having a CPU, a north bridge chip and a south bridge chip. The debug device consists of a processing unit, a comparing unit and a recording unit. The processing unit receives a first address signal and a second address signal from the north bridge chip, and correspondingly transmits an index signal and a test data to the north bridge chip. The comparing unit compares the first and the second address signal to generate a comparing signal. And the recording unit records the first and the second address signal and the comparing signal. The north bridge chip connects to the south bridge chip via a bus, and the debug device also connects to the south bridge chip. Therefore the north bridge chip and the debug device transmit to both through the south chip.

A method of computer power state management. When an operating system thereof is idle and the processor thereof transits to a clock-suspended power state (C3/C4 state), an arbitrary bit is asserted to prevent requests from being passed through the Northbridge. When the processor is in the C3/C4 state, if a break event is received, the Southbridge transmits the break event to the Northbridge and changes the processor state from C3/C4 to C0 simultaneously. The break event is subsequently transmitted to the processor when the arbitrary bit is disabled.

Method for testing chip configuration settings

A control method of synchronizing operation frequencies of a CPU and a system RAM in a power management process. A power management process is initialized by a system interrupt generated by a power management event. After sending the interrupt control signal output from the chipset to the CPU, the CPU enters a system management mode to execute an interrupt service routine. The interrupt service routine irrelevant to the system RAM configuration is executed first. The shadow RAM control register of the chipset is programmed using the BIOS program to enable the BIOS ROM. A distant jump command is programmed to jump into a predetermined memory address of the BIOS ROM storing a system RAM frequency modulation program to execute the system RAM frequency program. Therefore, the operation frequencies of the CPU and the system RAM are consistent during the power management process to eliminate the instability of system caused thereby.
