Charge Coupled Devices in Signal Processing Systems. Volume III. Digital Function Feasibility Demonstration.

摘要

In 1973 the Navy began a program to investigate and demonstrate the impact of the use of charge coupled devices (CCDs) in the digital domain. The concept of digital signal processing with CCDs is discussed briefly. Two implementations of an adder circuit are described and the development of each implementation in arrays to perform arithmetic operations is shown. The experimental results derived from these individual adders and the overall arrays is presented along with some theoretical models. Also presented are the results of a study to determine an efficient means of interconnecting a number of independent processors; the digital CCD development program is expected to produce such independent data processors contained on one or two chips. The study describes a method of interfacing an arbitrary number of such processors that employs distributed network control and exhibits soft failure.
