The Design Of Digital Stored Oscillograph Display System Based On DSP

DSO(digital stored oscillograph) is the wide-spread use in modern electronic measure system. It is widely applied in many fields such as production,scientific research,defence. The part of display system is very important part to DSO.CRT based on raster-scan technique have many virtues such as low cost,high quality and multicolor.With the CRT, significance for market of reducing the cost of DSO and improving the ability of compete when use this technique. It is very necessary for research DSO display system who have many virtues such as simple structure,good performance,better compatibility and low cost. In this paper, a design of digital stored oscillograph display system based on DSP is presented. It receives control Information and corresponding collector data from the HOST by DSP HPI. A integrated display system is composed of HPI,data processing module whose core is DSP, display controll module whose core is programmable Advanced CRT Controlle(rHD63484)and terminal facility—CRT.The architecture of the system is firstly described. Then the performance of the major parts and the design of software are analyzed. At last the result of the design is discussed.
