Abstract

In this paper a speculative computation method for IEC 61499 function block (FB) systems is proposed to increase the level of parallelism when executing the FB system and thus to increase system's performance and to reduce response time on input events. Data and control dependencies in FB systems are recognized and defined as a basis for organizing speculative execution of FB algorithms. A simulation model of FB systems with speculative execution based on timed stochastic Petri nets is considered. In addition, the paper discusses the results of simulation experiments conducted in CPN Tools.
