Abstract

Feedback control applications are robust to occasional deadline misses. This opens up the possibility of saving scarce (computation and communication) resources on embedded platforms. Stability and performance requirements of a control loop impose restrictions on acceptable patterns of deadline misses (e.g., not too many misses in a row). Such requirements are captured by (m,k)-firmness conditions. That is, at least m control computation jobs must meet deadlines in any k consecutive jobs. (m,k)-firm design requires (i) representation of stability and performance requirements in terms of (m,k)-firm deadlines (ii) controller synthesis taking into account the (m,k)-firmness parameters (iii) schedule analysis to verify guarantees on meeting the firmness conditions. We present a co-synthesis framework for these three design components and illustrate its applicability with examples.
