Abstract

Sequential Monte Carlo techniques are among the principal tools for the on-line estimation of the state of a non-linear dynamic system. We propose a framework for the multithreaded implementation of the widely popular sampling importance resampling (SIR) method on hybrid CPU/FPGA systems. The framework is based on the multithreaded reconfigurable operating system ReconOS which allows for an easy repartitioning of threads between hard- and software. We demonstrate the framework on a case study for visual object tracking and evaluate the performance of different hardware/software partitionings.
