1. Rethinking Speculative Execution from a Security Perspective
Abstract : Speculative out-of-order execution is one of the fundamental building blocks of modern, high-performance processors. To maximize the utilization of the system's resources, hardware and software security checks in the speculative domain can be temporarily ignored, without affecting the correctness of the application, as long as no architectural changes are made before transitioning to the non-speculative domain.

2. Towards a Trustworthy Stack: Formal Verification of Low-Level Hardware and Software
Abstract : Computer systems, consisting of hardware and software, have gained significant importance in the digitalised world. These computer systems rely on critical components to provide core functionalities and handle sensitive data. READ MORE

3. Rethinking Dynamic Instruction Scheduling and Retirement for Efficient Microarchitectures
Abstract : Out-of-order execution is one of the main micro-architectural techniques used to improve the performance of both single- and multi-threaded processors. The application of such a processor varies from mobile devices to server computers. READ MORE

4. Leveraging Existing Microarchitectural Structures to Improve First-Level Caching Efficiency
Abstract : Low-latency data access is essential for performance. To achieve this, processors use fast first-level caches combined with out-of-order execution, to decrease and hide memory access latency respectively. READ MORE

5. Securing the Memory Hierarchy from Speculative Side-Channel Attack
Abstract : Modern high-performance CPUs depend on speculative out-of-order execution in order to offer high performance while also remaining energy efficient. However, with the introduction of Meltdown and Spectre in the beginning of 2018, speculative execution has been under attack. READ MORE
