The Design And Implementation Of The Embedded Systems Of The Spectrum Monitoring Equipment Based On S5PV210

With the wider radio application, plus the more complex radio environment, the demand for the spectrum monitoring equipment has become even more widespread. Because of the enhancement of the capabilities of the embedded device, it has displaced conventional computer system in many aspects, which also provides us with stronger performance, smaller size, and more controllable resource, so it is widely used in instrument manufacture.This thesis aims to fully implement an embedded system of monitoring equipment which is based on the high performance ARM processor S5PV210. It not only meets the requirement of the spectrum monitoring equipment spectrum monitoring device functions, but also provides various extended functions which the smart devices should equipped with and an excellent universal platform. Here are the main contents of the research:a. Accroding to the requirement of the hardware, it designs the framework of the hardware system and the master chip power supply circuit, emphatically design the HPI communication bus and high-speed data bus between the ARM and the signal processing unit, also design the intelligent devices such as network card, USB interface, serial hardware circuits and other related functions.b. Based on the software development requirements, we divide the embedded operating system into four layers, then make detailed structured analyses and designs for each layer. For the most imoportant part of the driver design and implementation, we propose the hierarchical designing idea, which assure the inheritance of the systems and driver.c. According to the driver architecture of the version 2.6 Linux kernel, this thesis completes the design and implementation of the bus drivers of the spectrum monitoring equipment signal processing system which is connected to the microprocessor core under the guidance of hierarchical idea. With the division thought, the thesis achevie the goal of controlling the FPGA of the frequency synthesis module by DMA access. It also equips with the temperature detecting driver, the LCD display driver, and the touchscreen driver, which also provides the control applications programs for software developers.d. It finishes the network and LCD driver features of the U-boot, also customizes the kernel software in commercialization. To lower the power consumption of the devices, some simplification for the kernel structure have been done.The whole system designed by this thesis has been verified by the actual experiments, it turns out to be quite stable, and achieves all the desired goals, the final spectrum monitoring equipment fulfills the requirements of a mature product, and provides a complete universal spectrum monitoring device embedded system plan and a inheritablthe software system.
