Digital storage oscilloscope system based on ZYNQ

Abstract

The invention relates to a digital storage oscilloscope system based on a ZYNQ platform. For the system, the IP multiplexing technology is adopted; an AXI4-Stream data stream transmission model is established; a FreeRTOS real-time operating system and a uC / GUI graphical user interface are comprehensively used for the first time for multi-task management and human-computer interface design. The digital storage oscilloscope system converts an analog electrical signal into a digital electrical signal; then the digital signal is stored in a local main memory through a trigger circuit; the memory data is accessed directly by a liquid crystal control subsystem; finally the functions of data acquisition and transmission, storage measurement and waveform display are realized. The digital storage oscilloscope system has the advantages of high integration, high transmission bandwidth, low power consumption and strong expansibility.

Description

technical field [0001] The invention belongs to the field of digital storage oscilloscopes in instruments and meters, in particular to a large-capacity data storage method based on a ZYNQ heterogeneous processor and a method for designing software and hardware of a liquid crystal display control system. Background technique [0002] The oscilloscope is to change the invisible electrical signal into the image signal visible to the human eye. Based on the rapid development of digital circuits and large-scale integrated circuits, the digital storage oscilloscope has become the electronic measurement field after the analog oscilloscope, digital phosphor oscilloscope and sampling oscilloscope. key technologies. Widely used in communications, medical, aerospace and high-energy physics and other fields. The design of the digital storage oscilloscope system is mainly divided into two categories in terms of hardware: one is a large-scale instrument with an industrial computer as the...

Problems solved by technology

This type of heterogeneous processing platform usually separates different processors on the circuit board, and uses circuit board metal wiring to connect each unit. Any change in the requirements will require redevelopment of hardware, and will greatly affect the efficiency of communication and data transmission between processors

Moreover, the transmission and storage of a large amount of data also brings high hardware cost overhead and system power consumption.
