Abstract
The present invention may provide a system with a fixed clock to provide a fixed clock signal, and a variable clock to provide a variable clock signal. The system may also include a chipset with a chipset time stamp counter (TSC) based on the fixed clock signal. A processor may include a fast counter that may be based on the variable clock signal and generate a fast count value. A slow counter may download a time stamp value based on the chipset TSC at wakeup. The slow counter may be based on the fixed clock signal and may generate a slow count value. A central TSC may combine the fast count and slow count value to generate a central TSC value.
