Trace hardware capture rates

If a Trace Port Interface Unit (TPIU) in continuous mode is used, all port widths from 1 to 32 can be output by the target. DDR clocking enables data to be output from the ETM on both edges of TRACECLK. This effectively halves the clock frequency for the same data rate.

Show/hideDSTREAM trace hardware capture rates

The maximum capture rate of the DSTREAM unit is 600 Mbps per trace signal using a 300MHz DDR clock signal. The capture buffer is 4GB in size.

Note

Some debuggers have limitations when tracing with DSTREAM. See the DS-5 Debugger documentation for details of the trace capabilities.
