The TPIU can be via the PMC MIO pins or the EMIO interface to the PL.
PMC MIO Data Interface
The maximum width of the trace data on MIO is 16 bits. The data is clocked out by a clock output from TPIU with a double data rate (DDR).
EMIO Data Interface
The maximum width of the trace data on EMIO is 32 bits. The data is clocked out by a clock input from the PL with a single data rate (SDR).
Frequency
The maximum clock frequency for the MIO and EMIO interfaces is speed grade dependent. See the PS Trace Interface section of the Versal Prime Series Data Sheet: DC and AC Switching Characteristics (DS956) and the Versal AI Core Series Data Sheet: DC and AC Switching Characteristics (DS957).
