Integrated Circuits for Avionics
Abstract
The main thrust of the Integrated Circuits for Avionics Program is to calibrate the chip area requirements and performance that can be obtained from custom VLSI circuits which have been designed to accomplish a specific communication signal processing task. The two primary areas of investigation were stringent narrow band filtering based on highly parallel VLSI systolic array architectures and vector processors based on the residue number theory and highly parallel VLSI pipelined architectures. Designs are included for custom VLSI programmable filters in both NMOS and CMOS technologies along with measured performance of higher order filters resulting form cascading the custom prototype chips. A unique multirate sampling scheme is presented for improving filter response. A unique custom VLSI design is included for a high performance pipelined residue processor using 16-bit operands and providing 32-bit results. Measured performance of this architecture is also included based upon testing of a prototype custom VLSI circuit. (KR)
