Abstract

Inherent possibilities of digital processing of broadband signals and images envisaging further development are considered. The greatest problems in this regard arise when we attempt to perform such integrated transformations as Fourier convolution and transformation, requiring a great many of operations of multiplication and addition. While amplification of velocity of switching of the basic elements has a theoretical limit, the degree of paralleling of multiprocessor systems is limited by the complexity of control devices. One of the ways of essential amplification of the processing systems' speed consists in execution of integrated transformations via specialized analog processors, which become a constituent of the common multiprocessor system. The role of such analog devices can be taken by echo-processors, among which the photon echo-processor (PEP) exceeds its analogs by many basic parameters. The latter has an important advantage, i.e. an ability to process both one-dimensional signals, and fields and images within one step of its work.
