title: Trace, Profiling and Diagnostics Monitor - TPDM
description:
The TPDM or Monitor serves as data collection component for various dataset
types specified in the QPMDA spec. It covers Implementation defined ((ImplDef),
Basic Counts (BC), Tenure Counts (TC), Continuous Multi-Bit (CMB), and Discrete
Single Bit (DSB). It performs data collection in the data producing clock
domain and transfers it to the data collection time domain, generally ATB
clock domain.
The primary use case of the TPDM is to collect data from different data
sources and send it to a TPDA for packetization, timestamping, and funneling.
