%X 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.
