用于數(shù)字示波器的處理器平臺設計
[Abstract]:Digital oscilloscope is the most common testing tool in the field of electronic measurement, which is widely used by researchers and engineers. Due to the continuous development of science and technology, various electronic devices are developing rapidly towards miniaturization and precision. The increase of signal frequency makes the influence of signal integrity on the normal operation of electronic equipment more and more. Because of its large size, traditional desktop oscilloscope is not suitable for field work, which increases the demand of portable oscilloscope. In addition, the traditional oscilloscope has limited measuring function and can no longer meet the needs of more diverse, more intelligent and multi-function is the trend of future development. Android operating system has the characteristics of easy development, diverse application and powerful function. It is suitable for the software environment of multifunctional oscilloscope. So it is very valuable to design a portable digital oscilloscope which is easy to use, automatic measurement and can be displayed intuitively. Moreover, the oscilloscope has the characteristics of supporting multi-touch control of fingers, colorful display, friendly operation interface and so on. The purpose of this project is to design a portable oscilloscope based on Android system. This paper mainly studies the hardware design of the core board used in digital oscilloscope. The core board of this design uses Samsung Exynos4412 chip as the core processor, and its main frequency is up to 1.5 GHz.. The design uses 1 GB DDR3 memory and 4 GB i NAND FLASH to form the minimum system, which provides the strong hardware processing ability for the platform as a whole. The processor platform is designed with a 10. 1 inch LVDS LCD and a capacitive touch screen to support five-point touch. The processor platform is also designed with USB interface, serial port, Ethernet port, SDIO,C2C and other interfaces, which can be easily connected with a variety of peripherals to achieve functional expansion. In addition, the printed circuit board of the digital oscilloscope processor platform core board is designed according to the design characteristics and related requirements of high-speed digital circuit, and the DDR SDRAM controller and circuit design are also studied.
