System Trace Macrocell

Getting Started

The Arm CoreSight System Trace Macrocell (STM) is a trace source that enables real-time instrumentation of software with no impact on system behavior or performance. For software, system and hardware engineers, visibility of the complete system is now critical. This is due to the need to deliver high performance, power optimized systems in shorter development cycles.

The Arm CoreSight System Trace Macrocell (STM) extends low-cost real-time visibility of software and hardware execution to all software developers. In particular application and kernel developers, enabling rich, optimized and low power software on Arm processor-powered devices across the whole supply chain.

Better trace for better software with Arm CoreSight

This white paper explores the limitations of existing software debug and trace technologies, and explains how the Arm CoreSight System Trace Macrocell (STM) and Trace Memory Controller (TMC) enable system level visibility to more developers. This reduces latency and increases throughput, at the same time as applying existing open source trace infrastructures.
