Distribution of Processing Tasks for the REMIDS II Real-Time Processor System

摘要

The demonstration system must perform many different operations to successfully locate minefields in real time. These operations fall into the categories of: Scanner data input, Scanner data processing, Inter-processor communication, and Display data output. The time-line also provides an overall view of the operations from which system-level requirements may be derived. For instance, it shows three parallel processes occuring concurrently on the DAP-610. Support of this concurrent processing from AMT would be necessary to keep program development costs down. Also there is a three-image-acquisition aperture time delay between first starting to acquire a scanner image and having results ready to display. This implies three images must be buffered in the DAP-610 in addition to any temporary storage needed for the algorithm execution. Finally, the time-line indicates a framing image display. Any additional computations for a scrolling display (vertical decimation, image shifting) would have to be distributed in time during the other processing and would have to be repeated at least ten times per second (preferably 30 times per second) to attain a smooth scroll appearance.
