3.4 CPU Load

This plot displays the CPU load for the data processing chain during the active or chirping section of a given frame/subframe and during the nonactive or interframe/intersubframe section of the frame/subframe (see Figure 3-6). The CPU load is expressed as a percentage of these active and inactive durations and therefore varies for a given profileCfg, but with a different frame rate. This plot shows the CPU load for the C66x DSP core (where the data path processing happens). For the advanced frame, this plot shows the CPU load for the first subframe, which has this plot enabled in the guiMonitor command (the plot title reflects this subframe number).

Note: Select Statistics in the Configure tab and configure the device accordingly to view this plot.
