Abstract
A hardware access layer (HAL) is combined with a configurable shadow mechanism, that copies the specified memory or register segments accessed in remote hardware by a program being debugged. The HAL may be involved in all interrupt handling for the remote hardware. By making this shadow mechanism configurable during runtime, and using a standard debugging techniques, a developer can specify watchpoints to break program execution based on changes in the remotely attached hardware as indicated in the specified shadow register segments.
