Problems solved by technology

Since each piece of DSP requires a large number of control circuits, the integration of the device is not high, and it is not easy to be integrated on a large scale; and this method is basically a calculation performed by software, so there is a limit on high speed; in addition, the calculation can only be performed in one The restoration operation of frame data starts after the end, that is, the restoration operation and control operation are performed in series, so the calculation delay is relatively large

Abstract

The invention relates to a pulsating array processing circuit for implementing wavefront control operation of a self-adapting optical system, arranging multiple processing elements into two linear structures to respectively complete convolution and recursion operations and using an addition processing element to link the two arrays together to implement the wavefront control operation; and n voltages are serially calculated in time-division multiplexing mode in an array, and the processing elements implement data transfer between adjacent elements by shift registers, avoiding memory read-write operation. And the arrays of the invention have features of data communication localization, and simple data and control streams, saving resources and convenient to implement with hardware.

Description

technical field [0001] The invention relates to a pulsation array processing circuit, in particular to a wave front control operation suitable for a wave front processor of an adaptive optical system. Background technique [0002] In the adaptive optics system, in order to effectively correct the dynamic wavefront error caused by atmospheric turbulence, the computing power and real-time performance of the wavefront processor are very high. The general-purpose microcomputer can no longer meet the requirements, and a special high-speed wavefront processor must be developed according to the characteristics of the wavefront processing of the adaptive optics system. The workflow of the wavefront processor includes five modules: image processing, slope calculation, wavefront restoration, control operation and D / A conversion. Among them, the wavefront control operation is the wavefront error vector E output from the restoration operation module, which is controlled and iterated Ca...
