Efficient inter-thread communication on the reconfigurable ρ-VEX

This thesis documents the implementation of atomic instructions for the ρ-VEX (reconfigurable VEX). These instructions enable threads to communicate enabling efficient multithreading. Furthermore, we investigate the possibility to use inter-thread communication to improve performance of static ρ-VEX configurations without significantly...

Deterministic execution of multithreaded applications for reliability of multicore systems

Constant reduction in the size of transistors has made it possible to implement many cores on a single die. However, smaller transistors are more susceptible to both temporary and permanent faults. To make such systems more reliable, online fault tolerance techniques can be applied. A common approach for providing fault tolerance is to per- form...

Multithreading for Embedded Reconfigurable Multicore Systems

In this dissertation, we address the problem of performance efficient multithreading execution on heterogeneous multicore embedded systems. By heterogeneous multicore embedded systems we refer to those, which have real-time requirements and consist of processor tiles with General Purpose Processor (GPP), local memory, and one or more...

Field Of Threads: Master’s Thesis on a tool for clarifying thread behavior

Multithreaded programming is becoming increasingly important because of recent increase in the use of multiprocessor computing. Multithreaded or concurrent programming is inherently more complex than single threaded code, requiring the use of synchronization and causing possible problems like deadlock or dormancy. Dynamic analysis tools can aid...

Hand held analog television over WiMAX executed in SW

This paper describes a device capable of performing the following tasks: it samples and decodes the composite video analog TV signal, it encodes the resulting RGB data into a MPEG-4 stream and sends it over a WiMAX link. On the other end of the link a similar device receives the WiMAX signal, in either TDD or FDD mode, decodes the MPEG data and...
