  abstract= "In this paper we present the results of our simulation and
     study of an optoelectronic SIMD architecture on a medium
     sized transputer array (18 processors). The particular
     optoelectronic architecture we have simulated is a Binary
     Image Algebra (BIA) Processor of considerable computational
     power -processing data at rates well in excess of those
     currently achievable using electronic computers. Considering
     the inherent parallelism of such an architecture, along with
     the need for very large amounts of data processing in order
     to perform realistic simulation, the simulator was
     implemented in occam on a transputer array. The process
     model of computing adopted by occam is also most appropriate
     to the optoelectronic architecture which we have designed
     because of its modularity: we have been able to design
     process structures which have the same topology as the
     processing modules in our architecture. In the
     optoelectronic architecture, data are transmitted to a set
     of processing modules, one of which is chosen to perform a
     particular operation; the data pass through that module and
     are are transformed as they do so; in our simulator the
     processing takes place in a very similar way: data are
     transmitted from the controller to the farm; a particular
     process/module of code is called, and the data are passed
     through it, using occam channels, and are processed as they
     do so.We begin with a description of BIA itself. The core of
     the paper is a description of the logical architecture we
     have adopted; we include an account of a method for reducing
     the limiting effect of the transputer link bandwidth on the
     performance of farming computationally undemanding tasks.
     The paper is concluded with a brief description of our
     design for an optoelectronic SIMD architecture."
