Hardware Implementation of a Digital Sensor Signal Processor

摘要

The implementation of digital signal processing techniques in a small, fieldable microprocessor requires careful attention to precision, environmental, and availability constraints. Sandia Laboratories is presently engaged in a program for BISS to design a processor named the MILES Adaptive Digital Processor (MADP) for installation in the field to process the signals from the MILES transducer. The heavy use of multiplication and lengthy summations has dictated the selection of a 16-bit word length processor with considerable mathematical power. Year-round operation in an unprotected enclosure has forced the use of low-power, broad-temperature-range hardware. In addition, hardware has been selected which has wide use in the military community to have the advantage of a well developed system. Development of a system for deployment is underway using a 16-bit microprocessor employing I exp 2 L technology. An overview of this program from the hardware design standpoint is presented.
