  3. 3. Efficient Memory Access and Synchronization in NoC-based Many-core Processors

    Författare :Xiaowen Chen; Zhonghai Lu; Umit Ogras; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Many-core; Network-on-Chip; Distributed Shared Memory; Microcode; Virtual-to-physical Address Translation; Memory Access Fairness; Barrier Synchronization; Cooperative Communication; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In NoC-based many-core processors, memory subsystem and synchronization mechanism are always the two important design aspects, since mining parallelism and pursuing higher performance require not only optimized memory management but also efficient synchronization mechanism. Therefore, we are motivated to research on efficient memory access and synchronization in three topics, namely, efficient on-chip memory organization, fair shared memory access, and efficient many-core synchronization.

    Sammanfattning : The goals set by the International Technology Roadmap for Semiconductors (ITRS) for the consumer portable category, to be realized by 2020, are 1000X improvement in performance with only 40\% increase in power budget and no increase in design team size. To meet these goals, the challenges facing the VLSI community are gaps in architecture efficacy, design productivity and battery capacity. LÄS MER
