View rendering system, spectrum analyzer, and rendering method

Abstract

The invention provides a view rendering system, a spectrum analyzer and a rendering method, belonging to the technical field of view rendering, in particular to a view rendering system, a spectrum analyzer and a rendering method. Includes a first element buffer unit and a second element buffer unit, wherein the first element buffer unit is used for continuously rendering a continuously changing rendering element of a view during sweep analysis; The second element buffer unit is used for rendering the invariant or passively changed elements of the view in the sweep frequency analysis process, and separates the rendering of the invariant or passively changed elements from the rendering thread, and performs independent rendering in the second element buffer unit only when the elements are changed. The second element buffer unit is used for rendering the invariant or passively changed elements of the view. The invention effectively avoids repeated rendering calculation of elements in the view which are unchanged or passively changed in the view rendering process, realizes the rendering calculation only when needed, and has the positive effects of effectively improving the analysis efficiency and saving the power consumption.

Description

technical field [0001] The invention belongs to the technical field of view rendering, and in particular relates to a view rendering system, a spectrum analyzer and a rendering method. Background technique [0002] The view rendering process is the process after the ModelAndView is obtained, that is, the view rendering process is to pack the model into a map form and bring it to the server through the request attribute. [0003] Spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation degree, spectral purity, frequency stability and intermodulation distortion. It can be used to measure certain components of circuit systems such as amplifiers and filters. Parameter, is a multipurpose electronic measuring instrument. [0004] The embedded spectrum analysis software (hereinafter referred to as the spectrum analysis software) carried by the handheld spectrum analyz...

AI Technical Summary

Problems solved by technology

[0005] The view of the spectrum analysis software is composed of multiple elements. There are many rendering elements and a large amount of calculation. This single-layer double-buffer rendering method will change the content that does not change or passively change during the continuous measurement process, such as logarithmic distribution in the view. Elements such as the background grid, reference amplitude, and scan information are repeatedly rendered along with the continuously changing signal curve. This repeated rendering containing a large number of floating-point logarithmic calculations will continue to consume CPU resources and prolong the single Rendering time and increased battery power consumption, thereby reducing the analysis efficiency and battery life of the handheld spectrum analyzer
