WebCommercial-off-the-shelf (COTS) platforms feature several cores that share and contend for memory resources. In real-time system applications, it is of paramount importance to correctly estimate tight upper bounds to the delays due to memory contention. However, without proper support from the hardware (e.g. a real-time bus scheduler), it is difficult to … WebA real - time task is assumed to be a set of components having some properties independently from any real - time operating.
