Middelburg %J Scientific Annals of Computer Science %D 2011 %I Alexandru Ioan Cuza University of Iasi %X In this paper, we study the phenomenon that instruction sequences are split into fragments which somehow produce a joint behaviour. In order to bring this phenomenon better into the picture, we formalize a simple mechanism by which several instruction sequence fragments can produce a joint behaviour. We also show that, even in the case of this simple mechanism, it is a non-trivial matter to explain by means of a translation into a single instruction sequence what takes place on execution of a collection of instruction sequence fragments. %K Fragmented instruction sequence execution %K polyadic instruction sequence %K program algebra %K basic thread algebra %U http://www.infoiasi.ro/bin/download/Annals/XXI2/XXI2_4.pdf
