Method and device for configuring data source for display unit dynamically

Abstract

The invention discloses a method and device for configuring data source for display unit dynamically. The method comprises the step 204 using data flow feedforward control, wherein data flow rate is monitored dynamically, secondly unit flow is displayed according to unit time, and unit relative data volume is calculated and displayed dynamically. The mathematic model is as follows: assuming that the function of data volume Q changed with the time t is F (t) = Q, the flow rate in the time t0 is shown below; assuming that the rate for displaying unit data volume by the screen is q and the function of data volume Qp corresponding to one display unit and time t is Qp = f(t), f(t) = dF(t)/(dt*q); and the device comprises a data flow monitoring unit, a dynamic data configuration unit and a dynamic interpolation compensation unit. The invention adopts data flow feedforward control to solve the data source problem configuration problem of the display units of the display medium and provide data source with stable and controllable flow rate and flow for the display units; and the method is particularly suitable for the waveform with high demand on real-time display or for the treatment and display of graphic data sources. The method and device for configuring data source for display unit dynamically of the invention can be widely used in the display process of wave graphics.

Description

technical field The present invention relates to a method for controlling and processing a data source and a device using the processing method, in particular to a method and device for dynamically configuring a data source for a display unit. Background technique In many fields, it will involve sampling various signals, converting them into data, and then displaying waveforms, graphics, etc. from a display medium (such as a display). Due to the sampling circuit itself, signal data transmission and other reasons, the flow rate and flow of the data source are not constant. When allocating the data of the display unit, it cannot be evenly distributed, and there is a problem that the data does not correspond to the display unit; In the case of co-processing between signal data streams, precise data flow rate and flow rate are required; however, the instability of the flow rate and flow rate of the data source often causes the final display effect to be distorted, stuttered, an...
