Problems solved by technology

[0003] In the U.S. Patent No. US8166283B2 entitled "Generator of ASignal with An Adjustable waveform" issued on April 24, 2012, an arbitrary waveform generator based on an instruction architecture is proposed. However, the arbitrary waveform The instructions of the generator are too loose and coupled, which is only suitable for the synthesis of simple waveforms, which is not conducive to the rapid and efficient synthesis and generation of complex sequence waves

Abstract

The invention discloses an arbitrary waveform generator based on an instruction framework. Aiming at the characteristics of the tight coupling between the address generator and the sequence generator in the traditional complex sequence waveform synthesis method, it is proposed to replace the sequence generator with a waveform synthesis instruction set controller to realize The time-sharing scheduling of waveform synthesis instructions and waveform segment waveform data reading reduces hardware complexity, thereby quickly and efficiently synthesizing and generating complex sequence waves.

Description

technical field [0001] The technical field of the arbitrary waveform generator of the present invention, more specifically, relates to an arbitrary waveform generator based on an instruction framework to generate complex sequence waves. Background technique [0002] Arbitrary Waveform Generator (AWG) is a type of signal source that has developed rapidly in recent years. It can not only generate standard waveforms such as sine waves and square waves generated by general signal sources, but also generate frequency shift modulation, amplitude modulation, etc. Various modulation signals, and also has the characteristics of continuous output waveform phase, stable waveform quality, and high bandwidth. Therefore, arbitrary waveform generators are widely used in disk drive testing, serial data communication, baseband / IF modulation testing, automotive anti-lock braking, engine control, frequency converters, and biomedical simulations.
