Abstract:

This report deals with the design of a computer system for the real- time processing of high-resolution video, photometric and long-wavelength infrared data. An analysis of the data rates generated by the various sensors and the algorithms involved in the subsequent data analysis indicates that the combined processing requirements are in the order of 100 MIPS million instructions per second, and that up to 16 Mbytes of high-speed memory may be needed. This processing power cannot be achieved with a sequential computer, and a parallel-processor architecture was therefore developed to achieve the necessary throughput. It has a very attractive costperformance ratio and appears to be useful in a number of other application areas such as radar, sonar, data-base search and update, mapping, solution of partial differential equations and simultaneous linear equations. The conclusion is drawn that the G- 471 is a computer system which, for the signal and image processing fields, provides a processing-powercost ratio which is at least an order of magnitude higher than that of large-scale sequential scientific computers. It is well suited to handle the near-real time processing requirements at AMOS.
