Abstract:
1. A virtual system management mode device, for processing a system management interrupt (SMI) signal generated by a special process, the virtual system management mode device comprising: a transformation unit for transforming the system management interrupt signal into a virtual system management interrupt signal; a control unit memory for storing a plurality of system management interrupt processes; a control unit for executing one of the system management interrupt processes according to the virtual system management interrupt signal; and a central processing unit, wherein when the executed system management interrupt process has to obtain a selected value of a selected unit, the control unit further determines whether the executed system management interrupt process is able to access the selected value of the selected unit, wherein when the executed system management interrupt process is not able to access the selected value of the selected unit, the control unit transmits a request signal to the transformation unit according to the executed system management interrupt process, and wherein the transformation unit transmits a CPU request signal to the central processing unit according to the request signal.
