Coresight (Part 7): The Two Main Functions of Coresight

Coresight (Part 7): The Two Main Functions of Coresight

Coresight has two main functions: debugging and tracing. 1. Debugging The debugger implements debugging functionality through DAP. 1.1. Single-Core Debugging System: One DAP, along with one AP and APBIC. External access to the DP is transformed by the DAP into AP access. The AP generates the AP bus through the APBIC, allowing access to debugging … Read more

Coresight Pitfall Diary – Funnel Component

Coresight Pitfall Diary - Funnel Component

Introduction: The previous article was only half written and not published yet, so here’s a quick note. Preface Recently, while working with Coresight, I had a persistent question: how does the funnel know which trace source corresponds to the input slave port? After discussing with the FAE from the chip manufacturer today, I finally understood … Read more

Coresight (Part 4) Channel Interface

Coresight (Part 4) Channel Interface

The channel interface is used for transmitting events between different Coresight components. It is implemented using two components: CTM: Cross Trigger Matrix, which receives CTI channel signals and broadcasts them to other CTIs. CTI: Cross Trigger Interface, which receives trigger signals, sends trigger signals, receives channel signals, and sends channel signals. Typical applications of the … Read more
