Effective dynamic memory disambiguation limits many practical approaches for code analysis, optimization, and debugging. An efficient solution to this problem could unlock additional performance and increase the reliability of computer systems.A potential avenue for overcoming the traditional limits of hardware memory disambiguation is through the use of signature registers. Such registers can operate on hundreds of addresses simultaneously and can be exposed to software through a flexible and general interface for use in a wide variety of systems. However, because signatures represent sets of addresses imprecisely, they are prone to false positives which limit their accuracy and effectiveness.This research investigates the effectiveness of exposing signature registers to software. Using scenarios from code analysis, optimization, and debugging as case studies, the effectiveness of signatures is compared to other hardware memory disambiguation techniques to evaluate their performance, complexity, and power costs. The hardware implementation for signature registers is investigated and refined to reduce false positives.

有效的动态内存消歧限制了许多用于代码分析、优化和调试的实用方法。一个有效的解决方案可以解锁额外的性能和提高计算机系统的可靠性。一个潜在的途径，克服传统的限制，硬件存储器消歧是通过使用签名寄存器。 这种寄存器可以同时对数百个地址进行操作，并且可以通过灵活和通用的接口暴露给软件，以用于各种系统。 然而，由于签名表示的地址集不精确，他们很容易误报，限制了他们的准确性和effectiveness.This研究探讨了有效性的签名寄存器暴露给软件。使用的情况下，从代码分析，优化和调试的案例研究，签名的有效性进行比较，其他硬件内存消歧技术，以评估其性能，复杂性和功耗成本。 签名寄存器的硬件实现进行了研究和改进，以减少误报。
