Timing requirements on multi-processing and reconfigurable embedded systems with multiple environments

In recent years, Multi-Processor System on Chip (MPSoC) devices are becoming more and more common in embedded systems, due to the possibilities and flexibility they offer. They allow running different environments simultaneously in a single platform, usually one for general purpose applications and another one for real-time processes. This is possible with a software technique such as hypervisors or Asymmetric Multi-Processing (AMP) frameworks, however, they can significantly affect the system in terms of latency. This work summarizes the main latencies a reconfigurable multi-core device with virtualized environments can have and proposes methods to measure and quantify latencies.
