1 * ARC Performance Counters
2
3 The ARC700 can be configured with a pipeline performance monitor for counting
4 CPU and cache events like cache misses and hits. Like conventional PCT there
5 are 100+ hardware conditions dynamically mapped to up to 32 counters

7 Note that:
8 * The ARC 700 PCT does not support interrupts; although HW events may be
9 counted, the HW events themselves cannot serve as a trigger for a sample.
