  1. 1. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques

    Författare :Andreas Sembrant; David Black-Schaffer; Erik Hagersten; David A. Wood; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. LÄS MER

  2. 2. Order in Ruins : British Society and the Media Assemblage of The World at War c. 1970-1975

    Sammanfattning : This thesis studies a period of intense crisis and creativity in British media, society, and culture, when the settled outcome of the Second World War (WW2) was perceived to be disintegrating. The post-world-war order was becoming an ‘order in ruins’. LÄS MER

  3. 3. Advances Towards Data-Race-Free Cache Coherence Through Data Classification

    Författare :Mahdad Davari; Kaxiras Stefanos; Erik Hagersten; Alberto Ros; Manuel Eugenio Acacio Sánchez; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shared Memory Architectures; Multicore; Memory Hierarchy; Cache Coherence; Data Classification;

    Sammanfattning : Providing a consistent view of the shared memory based on precise and well-defined semantics—memory consistency model—has been an enabling factor in the widespread acceptance and commercial success of shared-memory architectures. Moreover, cache coherence protocols have been employed by the hardware to remove from the programmers the burden of dealing with the memory inconsistency that emerges in the presence of the private caches.

  4. 4. Securing the Memory Hierarchy from Speculative Side-Channel Attack

    Författare :Christos Sakalis; Magnus Själander; Sven Karlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : 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. LÄS MER

  5. 5. Reconfigurable-Hardware Accelerated Stream Aggregation

    Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream; Reconfigurable Computing; Aggregation; Dataflow; FPGA; Memory Hierarchy; Compression;

    Sammanfattning : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. LÄS MER
