Commercial Off-The-Shelf (COTS) processors are now commonly used in real-time embedded systems. The characteristics of these processors fulfill system requirements in terms of time-to-market, low cost, and high performance-per-watt ratio. However, multithreaded (MT) processors are still not widely used in real-time systems because the timing analysis is too complex. In MT processors, simultaneously-running tasks share and compete for processor resources, so the timing analysis has to estimate… CONTINUE READING
