General Information
The System Trace Macrocell (STM) is a component within the Arm Coresight technology ecosystem designed to enhance the tracing capabilities of embedded systems. It provides a mechanism for capturing and analyzing system events, allowing developers to gain insights into software behavior, performance, and debugging.
STM is particularly beneficial for real-time applications, as it enables the collection of trace data with minimal impact on system performance. This makes it an essential tool for developers working on complex embedded systems, where understanding the timing and sequence of events is crucial.
STM can be seen as an expansion of the Instrumentation Trace Macrocell (ITM). While ITM focuses on providing a lightweight mechanism for tracing software events, STM extends these capabilities by allowing for more extensive system-level event tracing.
