1.2 HWI Hardware Interrupt Benchmarks
HWI_enable.This is the execution time of a HWI_enable function call,which is used to globally
enable hardware interrupts.
HWI_disable.This is the execution time of a HWI_disable function call,which is used to globally disable hardware interrupts.
HWI dispatcher.These are the execution times of specified portions of the HWI dispatcher code.
This dispatcher handles running C code in response to an interrupt.The benchmarks provide
times for the following cases:
•Interrupt prolog for calling C function.This is the execution time from when an interrupt
occurs until the user??s C function is called.
•Interrupt epilog following C function call. This is the execution time from when the user‘s C
function completes execution until the HWI dispatcher has completed its work and exited.
