Can I determine timing metrics on my target, which has limited RAM and/or ROM?

The instrumentation overheads for RapiTime tools are very low, and zero-instrumentation overhead can even be supported in some cases, depending on your target hardware and data collection strategy. This means that you can use RapiTime with virtually any target. 

If your available memory is very limited, you can use RapiTime's Time Bands feature to automatically select the depth of instrumentation of your code based on the expected execution frequencies of your code.
