Hello, I have a few questions about the uVision simulator for the Cortex-M4 floating-point instructions.
1. Does the uVision simulator model Cortex-M4 floating-point instructions cycle-accurately? I tried the uVision v4.14.4 evaluation version. I got the Time (%) bars in the Performance Analyzer window, but the Timer (sec) was always 0. Besides, I didn't find a way to display cycle counts with the Performance Analyzer.
2. If the answer to 1 is 'yes', where can I find a step-by-step description to measure cycle counts?
3. If the answer to 1 is 'no', is there an alternate way to measure the cycle count for floating-point instructions?
Thanks in advance, -Robby
Bradford,
Thank you very much - the "States" field under "Registers/Internal" seems to track even while single-stepping.
As a new (ignorant) user, I searched through the Help documentation for cycles and CPU cycles and cycle-accurate, and a whole lot of other key words. I never would have searched for states. After receiving your Email, I went through the IDE User's Guide and under "Registers" it never mentions "States". You may very well have written the only documentation that exists.
Thank you very much,
