Title:
FPGA-BASED DATA FLOW PROCESSING METHOD AND APPARATUS, AND PG DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116320
Kind Code:
A1
Abstract:
Disclosed in the present invention are an FPGA-based data flow processing method and apparatus, and a PG device. The method comprises: obtaining a first image data flow, a video timing signal, and the number of sampled pixels per pixel clock of a display module to be tested; converting the first image data flow into a second image data flow having a first bit width transmitted per pixel clock cycle, wherein the first bit width is determined according to a preset maximum number of sampled pixels and a preset maximum color depth; enabling the second image data flow to pass through transmission channels the number of which is equal to the number of sampled pixels to convert the second image data flow into third image data flows, wherein the third image data flows are parallel image data flows having the number of sampled pixels transmitted per pixel clock cycle; and synchronizing each image data flow in the third image data flows with the video timing signal, to obtain parallel video data flows. Thus, the parallel video data flows are not only suitable for the display module to be tested having the maximum bit width, but also can be downward compatible with other types of display modules to be tested, thereby achieving good compatibility.
