Problems solved by technology

However, the way in which the computer uniformly generates all waveform data is relatively slow, and a large amount of data needs to be transmitted in the bus, which cannot realize real-time scheduling of arbitrary waveforms.
[0004] In addition, the arbitrary waveform and arbitrary seq

Abstract

The invention discloses an arbitrary waveform generating system based on a user-defined processor. In a control portion, a waveform generating module generates various waveform segment data downloaded to a hardware portion through a waveform downloading module, a control program generating module receives an externally inputted instruction set, and the instruction set is downloaded to the hardware portion after compiling of a compiling module. In the hardware portion, a storage control logic module controls reading and writing of a waveform memory, the user-defined waveform processor receives and analyzes the instruction set, generates call instructions for corresponding waveform segments according to names of the waveform segments indicated by the instruction set, transmits the call instructions to the storage control logic module and receives the waveform segment data read by the storage control logic module, and analog signals are outputted after combined waveform segment data are conditioned according to the call sequence and the call frequency of the waveform segment indicated by the instruction set. By the aid of the arbitrary waveform generating system, data transmission time of the control portion and the hardware portion during waveform generation can be shortened.

Description

technical field [0001] The invention relates to the technical field of arbitrary waveform generators, in particular to an arbitrary waveform generation system based on a custom processor. Background technique [0002] Arbitrary waveform generator, as one of the common test and measurement instruments, has experienced many years of technical development. Similar products that are widely used and promoted in the market are mainly divided into desktop instruments and bus-type virtual instruments. The desktop instrument is relatively independent, but its volume is relatively large, and the scope of use environment is small, so it has certain limitations in the realization of remote operation and system integration. The bus-type virtual instrument has unique advantages in system integration and remote operation. [0003] At present, the arbitrary waveform generator based on the bus can generate standard waveform, arbitrary waveform, arbitrary sequence and other functions. Howe...
