The ARM CoreSight Trace Memory Controller (TMC) supersedes the traditional ETM and ETB. It can be configured (at synthesization time of the device) to act as a trace capture unit that outputs trace data on dedicated trace pins (similar to traditional ETM configuration) or as a trace capture unit that stores trace data in a RAM buffer. In contrast to traditional ETB, this buffer does not have to be on-chip RAM but may also be external high-speed RAM. There are also some other configurations possible, but not really spread in the field right now and therefor not really used.
