IAR Embedded Workbench for RH850 3.20.x

Briefly about performance analysis

In this section:

The performance analysis is capable of measuring these execution aspects:

  • the total number of executed instructions

  • the number of executed instructions that trigger branching

  • the number of accepted interrupts and other exceptions

  • the total number of clock cycles

  • the number of clock cycles, excluding the interrupt processing

  • the number of cycles in which DI/EI interrupts are disabled

  • the number of instruction fetch requests, and instruction cache non-wait responses for instruction fetch requests, issued by the IFU

  • the number of flash ROM data requests.

The analysis can cover either the entire execution or execution between two breakpoints.

Performance analysis settings cannot be changed during the execution and the results of the analysis are displayed in the Performance Analysis window.
