Set TriCore Perfomance Counters

In this topic:

Introduction

Configuration

 

 

Introduction

Performance Counters are used to measure various aspects of a program's performance and can be valuable tools for analyzing and optimizing the performance of software applications. You can use winIDEA performance counters to:

identify areas that consume the most resources

reveal cache misses or pipeline stalls, which can impact the overall performance of an application

optimizing code by reducing cache misses or improve branch prediction

get information about resource usage, such as CPU cycles, time spent executing functions, instruction counts, and memory access patterns

gather data and diagnose the root cause of performance issues.

 

 

Configuration

Carefully follow the next instructions to setup the performance counters to count between two hardware breakpoints.

 

number1

Select Configure from the Counters context menu.

Plugin-tricore-ExtendedContextMenu

 

 

number2

Configure Counters as shown below.

It is important that Counter Mode is set to Task.

 

TriCorePluginEdit

 

number3

Open Debug | Hardware Breakpoints and enable two breakpoints.

TriCore_Plugin_multicore4

 

Number4

Click the "..." button and open the Browsing Functions dialog.

Switch to the Functions tab and select:

start function for the 0 breakpoint (First breakpoint is hit when CPU starts to execute start function.)

stop function for the 1 breakpoint (Second breakpoint will be hit when CPU starts to execute stop function.)

 

TriCore_Plugin_multicore5

 

 

Number5

Configure the first Comparator via "..." button.

Make sure you set:

Event associated (EVTA) to None

Break-Out Disable (BOD)

Counter (CNT) to Start performance counters

 

TriCorePluginEdit2

 

number6

Click on the "..." button to open the second Comparator dialog.

Make sure you set:

Event associated (EVTA) to Halt,

Counter (CNT) to Stop performance Counters.

 

TriCorePluginEdit3

 

number7

Run the application and observe the values.

To get the time value of CPU clocks (hold by CCNT) has to be to multiplied with the CPU clock period.

All these registers are memory mapped, therefore the same data can be observed in the Special Function Registers or Memory Window.
