Hi, I never use TSIM. I don’t know much about LEON and TSIM. You should ask the question to Jiri Gaissler.

Thanks

I want to optimize a program that I wrote and simulate it thanks to TSIM but I don’t know how to interpret the results.
If I take the same example:

Cycles : 1399497
Instructions : 906783
Overall CPI : 1.54

CPU performance (50.0 MHz) : 32.40 MOPS (32.40 MIPS, 0.00 MFLOPS)
Cache hit rate : 98.7 % (100.0 / 80.0)
AHB bandwidth utilisation : 33.7 % ( 0.4 / 33.3)
Simulated time : 27.99 ms
Processor utilisation : 100.00 %
Real-time performance : 11.86 %
Simulator performance : 3843.69 KIPS
Used time (sys + user) : 0.24 s

I want to reduce the execution time of my program but I don’t understand all these parameters. Which parameters are important and what do I have to reduce? The simulated time or the Used time? Can you clearly explain what represent “system” and “user” in the used time?

Thanks
