Arduface: an embedded system analysis tool

An embedded system combines many hardware and software components. The more hardware and software components are used in an embedded system, the more complicated relationships occur. In order to understand the embedded system appropriately, it is necessary to have high-level expertise in both hardware and software components. However, not all the developers are expert in these two components. This research aims to resolve hardware and software components mapping problem in the embedded systems. The software model graph and the hardware model graph were extracted from source code and device configuration respectively. Using a customised graph matching technique, our method automatically identifies the code block corresponding to any hardware components selected. Our experimental results show that our method exhibits high precision for most hardware components, but low recall in general. We discuss the reason and suggest possible extensions.
