Univers PROF2: PROFESSIONAL PROFILER

General Description

Univers PROF2 is a professional, accurate, static and dynamic profiling tool.

To find performance bottlenecks or to optimize an algorithm in a structured way, a profiler is required. The profiler must be fully accurate to base design decisions upon. The Univers profiler is accurate and incorporates many features to help you to develop and optimize the critical application source code.
 

Accuracy

Often profilers use system resources, or they extend the code with small pieces of code per function. The disadvantage is twofold: the profiling is inaccurate and you do not profile the original code.  When a profiler requires a timer it often means that profile data is gathered when the timer generates an interrupt. The timer's frequency might be user configurable but still this might be too inaccurate to profile an algorithm.

The Univers Profiler does not have the above mentioned disadvantages. The supported Instruction Set Simulators implement the timing of a CPU, including caches, branch miss-prediction, etc. These fast executing models lead to accurate profiling data.

 

Abstraction level

The Profiler can be used on a high abstraction level to decide which part of the code is best transferred from software to hardware to boost the application. The Profiler provides also detailed stall cause information on instruction level to optimize critical parts of the code on the lowest possible level.
 

Static Profiling

The static profiler gathers timing information on individual disassembly instruction level. This information is presented in tabular ASCII format or graphically. The graphical output shows the program and data memory space on the X-axis and 'cycle counts' on the Y-axis. For each instruction and procedure the total execution cycles, the stall cycles, the stall causes, the amount of read accesses, etc. is maintained an presented.
 
The source code procedures are shown on the X-axis. Highlighting such a procedure presents a box with the totals for that procedure.

When a procedure includes a loop and you want to know the totals for that loop, just select the loop's address range and another box presents the totals for that loop. (not shown in the figure)
 

Dynamic profiling

The dynamic profiler gathers timing information on individual disassembly instruction level. This type of profiling is very helpful to determine bus loads. On the X-axis the time is presented. On the Y-axis all kinds of 'count information' can be presented. The amount of gathered data can be quite extensive, therefore you can select the time interval in which data is accumulated. You can perform this type of profiling on memory accesses, input/output accesses, all sorts of counters, HDL signals, etc.
