1. 1. Performance Analysis of Application-Specific Multicore Systems on Chip

   Författare :Iyad Al Khatib; Axel Jantsch; Jari Nurmi; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicore; System on Chip; Performance; Information technology; Informationsteknik;

   Sammanfattning : The last two decades have witnessed the birth of revolutionary technologies in data communications including wireless technologies, System on Chip (SoC), Multi Processor SoC (MPSoC), Network on Chip (NoC), and more. At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimediaservices and biomedical applications. LÄS MER

3. 2. Ultra-low-power Design and Implementation of Application-specific Instruction-set Processors for Ubiquitous Sensing and Computing

   Författare :Ning Ma; Lirong Zheng; Zhonghai Lu; Zhuo Zou; Jari Nurmi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The feature size of transistors keeps shrinking with the development of technology, which enables ubiquitous sensing and computing. However, with the break down of Dennard scaling caused by the difficulties for further lowering supply voltage, the power density increases significantly. LÄS MER

4. 3. Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems

   Författare :Abdul Naeem; Axel Jantsch; Zhonghai Lu; Jari Nurmi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory consistency; Protected release consistency; Distributed shared memory; Network-on-Chip; Scalability;

   Sammanfattning : The shared memory systems should support parallelization at the computation (multi-core), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. These parallel systems supporting shared memory abstraction both in the general purpose and application specific domains are confronting the critical issue of memory consistency. LÄS MER

5. 4. Hardware/Software Co-Design of Heterogeneous Manycore Architectures
