  1. 1. Rethinking Dynamic Instruction Scheduling and Retirement for Efficient Microarchitectures

    Författare :Mehdi Alipour; David Black-Schaffer; Stefanos Kaxiras; Mikko H. Lipasti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Out-of-Order Processors; Energy-Efficient; High-Performance; Instruction Scheduling; Computer Science; Datavetenskap;

    Sammanfattning : 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. LÄS MER

  3. 2. Leveraging Existing Microarchitectural Structures to Improve First-Level Caching Efficiency

    Författare :Ricardo Alves; David Black-Schaffer; Stefanos Kaxiras; Mattan Erez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Energy Efficient Caching; Memory Architecture; Single Thread Performance; First-Level Caching; Out-of-Order Pipelines; Instruction Scheduling; Filter-Cache; Way-Prediction; Value-Prediction; Register-Sharing.;

    Sammanfattning : 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. LÄS MER

  4. 3. Rethinking Speculative Execution from a Security Perspective

    Författare :Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. High-Performance Network-on-Chip Design for Many-Core Processors

    Författare :Boqian Wang; Zhonghai Lu; Kun-Chih Chen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network-on-Chip; Chip Multi Many-core Processors; Multiprocessor System-on-Chip; High-Performance Computing; Cache Coherence; Virtual Channel Reservation; Admission Control; Artificial Neural Network; AXI4; Quality of Service; Network-on-Chip; Chip Multi Many-core Processors; Multiprocessor Sys-tem on a Chip; High-Performance Computing; Cache Coherence; Virtual Channel Reser-vation; Admission Control; Artificial Neural Network; AXI4; Quality of Servic; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : With the development of on-chip manufacturing technologies and the requirements of high-performance computing, the core count is growing quickly in Chip Multi/Many-core Processors (CMPs) and Multiprocessor System-on-Chip (MPSoC) to support larger scale parallel execution. Network-on-Chip (NoC) has become the de facto solution for CMPs and MPSoCs in addressing the communication challenge. LÄS MER
