1. 1. An Automated and Controlled Numerical Precision Reduction Framework for GPUs

   Författare :Alexandra Angerd; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microarchitecture; Floating-Point Precision; Approximate Computing; Register File; GPU;

   Sammanfattning : Reducing the precision of floating-point values is an effective approach to achieve higher performance as well as higher energy-efficiency. This is especially true for GPUs, since many of its common tasks are inherently insensitive to precision-reduction. LÄS MER

3. 2. Approximation and Compression Techniques to Enhance Performance of Graphics Processing Units

   Författare :Alexandra Angerd; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compression; Approximate Computing; Register File; Machine Learning; Floating-Point Precision; Microarchitecture; GPU;

   Sammanfattning : A key challenge in modern computing systems is to access data fast enough to fully utilize the computing elements in the chip. In Graphics Processing Units (GPUs), the performance is often constrained by register file size, memory bandwidth, and the capacity of the main memory. LÄS MER

4. 3. Towards a Trustworthy Stack: Formal Verification of Low-Level Hardware and Software

   Författare :Ning Dong; Roberto Guanciale; Mads Dam; Magnus Myreen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Formal Verification; Information Flow; Refinement; Interactive Theorem Prover; HOL4; Serial Interface; Pipelined Processor; Microarchitecture; Out-of-order Execution; Formell Verifiering; Informationsflöde; Förfining; Interaktiva Bevisprogrammet; HOL4; Seriellt Gränssnitt; Pipelined Processor; Mikroarkitektur; Omordnad Exekvering; Datalogi; Computer Science;

   Sammanfattning : 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. LÄS MER

5. 4. Using wormhole switching for networks on chip : feasibility analysis and microarchitecture adaptation

   Författare :Zhonghai Lu; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Network-on-Chip (NoC) is proposed as a systematic approach to address future System-on-Chip (SoC) design difficulties. Due to its good performance and small buffering requirement, wormhole switching is being considered as a main network flow control mechanism for on-chip networks. LÄS MER

7. 5. 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.
