2.3.4 Profile and debug interface

This section describes the profile and debug interface in the DMC-620.

The DMC-620 provides programmable features that allow system designers and software developers to fine-tune performance and power settings for their applications. Several events can be monitored and the statistics that are used to enhance the performance of the controller by statically, or dynamically, altering the programmed state.

The information is made available through output pins that the system integrator must connect to an external monitoring unit.

The following events are monitored:

Each event is implemented as a pair of signals, VALID, and either PAYLOAD or a permanently valid PAYLOAD signal.

The profile and debug interface can be connected to a generic event counter block. Connecting to a generic event counter block enables any combination of the signals can be logged and tracked, depending on your system requirements.
