Abstract: A test system for overclocking capability of a central processing unit (CPU) includes a basic input and output system (BIOS), a frequency generator, and a watchdog timer. The BIOS includes an input module, a watchdog control module, and a frequency increasing module. The input module inputs an initial frequency of a CPU to the frequency generator to adjust a real-time frequency of the CPU. The watchdog control module sends a counter signal to the watchdog timer in a preset time interval. The watchdog timer receives the counter signal. If the watchdog timer does not receive the counter signal within the preset time, the watchdog timer outputs a reset signal to restart the computer. The frequency increasing module adds a preset increment to the real-time frequency to obtain a newly adjusted frequency, and provides the newly adjusted frequency to the frequency generator to adjust the real-time frequency.

Multiphoton microscopy is characterized in low invasion, low photo damage and high penetration. Hence, scanning through multiphoton microscopy does not hurt the bio tissue. It is thus fit for scanning live bio tissues to know its aging status. In addition, the quantitative analysis provides a precise index for diagnosing a damage severity of the tissue, like cancer.
