ROUTING RAW DEBUG DATA USING TRACE INFRASTRUCTURE IN PROCESSOR-BASED DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18498583 titled 'ROUTING RAW DEBUG DATA USING TRACE INFRASTRUCTURE IN PROCESSOR-BASED DEVICES

The patent application discusses routing raw debug data using trace infrastructure in processor-based devices.

• Processor-based devices have a trace interconnect bus, a subsystem circuit with a debug transmit circuit, and an I/O endpoint circuit.
• The debug transmit circuit receives raw debug data, generates a debug trace packet with the raw data, and transmits it to the I/O endpoint circuit via the trace interconnect bus during bus inactivity.
• This allows existing trace infrastructure to transmit raw debug data without the need for expensive tools to decode conventionally packetized trace data.

Potential Applications: - Debugging and troubleshooting in processor-based devices - Real-time monitoring of raw debug data - Enhancing trace infrastructure capabilities in devices

Problems Solved: - Efficient transmission of raw debug data - Cost-effective debugging solutions - Utilization of existing trace infrastructure for raw data transmission

Benefits: - Streamlined debugging processes - Reduced overhead costs - Improved analysis of raw debug data

Commercial Applications: Title: "Enhanced Debugging Solutions for Processor-Based Devices" This technology can be utilized in industries such as telecommunications, automotive, and consumer electronics for efficient debugging and monitoring of processor-based devices.

Questions about the technology: 1. How does this innovation improve the efficiency of debugging processes in processor-based devices? 2. What are the cost-saving benefits of using existing trace infrastructure for transmitting raw debug data?

Original Abstract Submitted

Routing raw debug data using trace infrastructure in processor-based devices is disclosed. In some aspects, a processor-based device comprises a trace interconnect bus, a subsystem circuit comprising a debug transmit circuit, and an input/output (I/O) endpoint circuit. The debug transmit circuit is configured to receive raw debug data from the subsystem circuit, and generate a debug trace packet comprising the raw debug data in lieu of formatted trace data. The debug transmit circuit is also configured to transmit the debug trace packet comprising the raw debug data to the I/O endpoint circuit via the trace interconnect bus during a period of trace interconnect bus inactivity. In this manner, an existing trace infrastructure can be employed to transmit raw debug data without incurring expense in terms of overhead and monetary cost due to the need for industry-standard, infrastructure-compliant tools to decode conventionally packetized trace data for analysis.
