The Summer Undergraduate Research Fellowship (SURF) Symposium
The debug unit of a modern digital system on chip (SoC) is a critical unit that allows users to monitor and analyze the chip’s activity that occurs throughout a SoC design. Selection of the debug unit’s correct feature set and architecture are critical to the success of the design. Debugging systems that exist have different architectures and are closely coupled to their host SoCs. As a consequence they are resource intensive to improve on due to the different nature of each SoC designs. Moreover, the bus protocols that allow the debug unit to interact with the SoC design are often …
