It's hard to know without seeing more code, but perhaps you are forgetting to change the second parameter of the PERF_BEGIN/PERF_END calls for the different sections?
... // Section 1 PERF_BEGIN(PERFORMANCE_COUNTER_BASE, 1); foo(); PERF_END(PERFORMANCE_COUNTER_BASE, 1); // Section 2 PERF_BEGIN(PERFORMANCE_COUNTER_BASE, 2); bar(); PERF_END(PERFORMANCE_COUNTER_BASE, 2); ... - Altera_Forum
