The application of parallel processing techniques based on transputers to astronomical instruments under development at the Royal Observatory Edinburgh is discussed. On the Cosmos plate-measuring machine, a data farm of transputers allows backgrounds to be determined in real time instead of requiring 1.5 h of offline VAX processing per plate. Transputers have been adopted as the embedded processors in a submm bolometer array instrument, and their use is planned in future applications such as thermal-IR array instruments and data compression applied to remote observing. The techniques of interfacing transputers to external hardware and to VAX/VMS computers are discussed. It is concluded that the use of transputers makes it possible to reconcile the requirements of performance, flexibility, and ease of use. The frequent existence of geometric parallelism allows easy exploitation of the power of parallel processing.
