    273 where it contains the total elpased time for processing a frame and a breakdown of the CPU time for each DSP stage. Taking the above frame as an example, the total elapsed time for processing frame 3740 is **0.2467ms**, and the CPU time spent on doing equalization is 0.0432896ms. The general takeaway here is that the framework is able to process the frame within the deadline of **0.375ms**.
