1. The CPU Clock Speed is assumed to be 720 MHz. If your board uses a different clock speed, then you must specify the new speed in RTW Options.
2. STS timing objects associated with subsystem profiling are configured for a host-side operation of 8*x, reflecting the numerical relationship between CPU clock cycles and high-resolution timer clicks. Therefore, STS Max, Total, and Average measurements are correctly reported in units of "instructions" or "CPU clock cycles".
