The concept of dataflow is usually limited to totally new computer structures. This paper
discusses the simulation of dataflow in a symmetric system of standard microcomputer
modules. The approach has advantages in that the parallelism of the computation can be
expressed and handled in a natural way. The simulation of the dataflow semantics takes,
however, hundreds of machine instructions for each actor execution and quite long actors
are needed to keep the overhead low. The implementation of a dataflow computation using …
