WebJul 6, 2024 · Operation counting is the process of surveying a loop to understand the operation mix. You need to count the number of loads, stores, floating-point, integer, and library calls per iteration of the loop. From the count, you can see how well the operation mix of a given loop matches the capabilities of the processor. origins frothy face wash review
