Assessment of Dynamic Look-Ahead Inter-Processor Connection Reconfiguration for Different Control Paradigms

Program execution methods and respective architectural solutions for parallel embedded systems with look-ahead dynamic inter-processor connection setting are discussed in the paper. The look-ahead dynamic connection setting is a novel method, which leads to time transparency of reconfiguration control during program execution. The look-ahead dynamic reconfiguration assumes segmentation of programs into sections, which are executed in parallel with connection setting for subsequent sections. The discussed architectures for the look-ahead dynamic reconfiguration are based on redundant resources such as processor links and link connection switches. The paper compares the efficiency of Strassen matrix multiplication in the systems based on multiple link connection switches, partitioned processor link sets and anticipated link connection setting on request in a single crossbar switch
