Abstract
Hardware-assisted watchpoint systems enhance the execu- tion of numerous dynamic software techniques, such as mem- ory protection, module isolation, deterministic execution, and data race detection. In this paper, we show that pre- vious hardware proposals may introduce signicant energy overheads, and propose WatchPoint Filtering (WPF), a novel ltering mechanism that eliminates unnecessary watchpoint checks. We evaluate WPF on two state-of-the-art proposals for hardware-assisted watchpoints usin...
