8.12. TPIU formatter and FIFO

This section describes the functionality of the formatter and the FIFO.

The formatter is the final unit on the ATB that inserts the ATID[6:0] into a special format data packet stream to enable trace data to be re-associated with a trace source.

The FIFO is 32 bits wide. To reduce the amount of logic required for this operation and that of the high-speed bridge, the FIFO is of an asynchronous design.
