  2. 1. Rethinking Speculative Execution from a Security Perspective

    Author : Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer architecture; speculative execution; processor; security; out-of-order execution; side-channel; microarchitectural replay; microarchitecture; Delay-on-Miss; Ghosts; Delay-on-Squash; Computer Science; Datavetenskap;

    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.

  4. 2. Finding and Exploiting Memory-Level-Parallelism in Constrained Speculative Architectures

    Author : Kim-Anh Tran; Alexandra Jimborean; Stefanos Kaxiras; Louis-Noël Pouchet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Memory-level-parallelism; Energy-efficiency; Performance; Compiler; Instruction Scheduling; SW HW Co-Design; Computer Science; Datavetenskap;

    Abstract : One of the main performance bottlenecks of processors today is the discrepancy between processor and memory speed, known as the memory wall. While the processor executes instructions at a high pace, the memory is too slow to provide data in a timely manner. READ MORE

  5. 3. Static instruction scheduling for high performance on energy-efficient processors

    Author : Kim-Anh Tran; Alexandra Jimborean; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Abstract : New trends such as the internet-of-things and smart homes push the demands for energy-efficiency. Choosing energy-efficient hardware, however, often comes as a trade-off to high-performance. READ MORE
