The application of an array processor to the real time generation of aircraft images in Air Traffic Control tower simulation is described. Particular emphasis is placed upon the problems which arise in achieving efficient utilisation of the array processor. It is shown that the time required to transfer data from the host to the array processor is a serious consideration in the partitioning of the algorithm between the two processors. It is also shown that array processor execution speed is about ten times faster than a host Fortran routine, provided that the array processor code is written to maximise the number of parallel computing elements used and to minimise loop lengths by pipelining of operations. These requirements result in a considerable software development effort. A timing analysis of the resultant array processor code is also presented. Originator-supplied keywords include Computer graphics, Real time operations, Pipelining computers, and Image synthesis.
