APIC: Advanced Programmable Interrupt ControllerACPI: Advanced Configuration & Power InterfaceACPICA: ACPI Component ArchitectureI needed a timer. A timer with a granularity of < 1msec and not tied to the Windows CE 1msec kernel tick. I wanted to program the timer hardware, raise an interrupt and signal an event to trigger specific code in my application.I used to do this with custom timer hardware in an FPGA design that resides on my Intel x86 based board (as a PCI device) and my own driver. ......
