  1. 1. Lock-Based Resource Sharing for Real-Time Multiprocessors

    Författare :Sara Afshar; Thomas Nolte; Moris Behnam; Reinder J. Bril; Enrico Bini; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Embedded systems are widely used in the industry and are typically resource constrained, i.e., resources such as processors, I/O devices, shared buffers or shared memory might be limited in the system. Hence, techniques that can enable an efficient usage of processor bandwidths in such systems are of great importance. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Embedded systems are typically resource constrained, i.e., resources such as processors, I/O devices, shared buffers or shared memory can be limited for tasks in the system. Therefore, techniques that enable an efficient usage of such resources are of great importance. LÄS MER

    Sammanfattning : The contemporary computers typically consist of multiple computing cores with high compute power. Such computers make excellent concurrent asynchronous shared memory system. LÄS MER

  5. 4. Schemes to Improve the Efficiency of Hardware Transactional Memory Systems

    Författare :Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transactional memory; parallel programming; chip-multiprocessor; multiprocessor;

    Sammanfattning : In todays ubiquitous multiprocessor environment parallel programming becomesan important tool to reap the maximum gain. But the traditional lock-based parallelprogramming model is not attracting average programmers as the level of expertiseneeded is very high. LÄS MER

  7. 5. Performance and Implementation Complexity in Multiprocessor Operating System Kernels

    Författare :Simon Kågström; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Operativsystem; multiprocessorer; implementationskomplexitet;

    Sammanfattning : The increasing use of multiprocessor computers require operating system adaptations to take advantage of the computing power. However, porting an operating system kernel to run on a multiprocessor can be very difficult because of a large code base, concurrency issues when dealing with multiple threads of execution, and limited tool support for development.
