The integration phase of real-time COTS-based systems is often problematic because when multiple tasks run concurrently, the interference at the bus level between cache fetching activities and I/O peripheral transactions is significant and causes unpredictable behaviors: experimentally, tasks can have computation time variance up to 50%. In this work, we present a theoretical framework able to model the interaction between CPU and peripherals contending for shared main memory through the front… CONTINUE READING
