    Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

  5. 9. Three Specialized Computer Architectures for Functional Program Execution

    Författare :Jonas Vasell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer architectures; G-machine; programming languages; program compilation techniques; VLSI implementation; performance; array architecture;

    Sammanfattning : Functional programming languages offer a new programming paradigm with many advantages over the more conventional imperative or procedural programming languages. However, these new languages are not as well adapted to the existing computers as the conventional languages, which results in low performance. LÄS MER

  7. 10. REMAP-γ: A Scalable SIMD VLSI Architecture with Hierarchical Control

    Författare :Lars Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; array signal processing; hierarchical control; SIMD; VLSI architectures; distributed synchronous clocking; embedded supercomputing;

    Sammanfattning : While the clock speed of general purpose (uni-)processors has risen dramatically during recent years, this is not true for SIMD (Single Instruction stream Multiple Data streams) parallel processors. The reason is to be found in the structure of this type of architecture: long-range broadcasting of data, clock and control signals. LÄS MER
