Method and apparatus for arbitrary resolution interval timeouts

Methods and apparatus for enabling timeouts with arbitrary resolutions to be implemented are disclosed. According to one aspect of the present invention, a method for enabling a device driver to communicate with a processor in a computing system includes exchanging information between the device driver and a clock system, and exchanging information between the clock system and a cyclic system. Information is also exchanged between the cyclic system and the processor. Although the clock system indirectly exchanges information with the processor, the clock system does not directly exchange information with the processor. In one embodiment, the clock system includes a callout system and a system clock, and exchanging information between the device driver and the clock system includes exchanging information between the system clock and the callout system, and exchanging information between the callout system and the device driver.
