We show that the interference between cache activity and I/O traffic generated by COTS peripherals can unpredictably slow down a real-time task by up to 44%. To solve this issue, we propose a framework comprised of 1) an analytical technique that computes safe bounds on the I/O-induced task delay; 2) a coscheduling algorithm that maximizes the amount of allowed peripheral traffic while guaranteeing all real-time task constraints.
