Usb Device

Universal serial bus is put forward by seven corporations which are led by the Intel. It cost lowly, fast and easily expandable. USB is widely used in serial communication interface, widely used in computer peripherals and digital products. The USB protocol layer is the core unit of the USB device, which handles most of the contents of the USB protocol provides. This paper studies USB protocol layer design and implementation. Then USB protocol layer is completed based on FPGA.

This paper describes the design and implementation of piping functionality for ARM based multi-process mono-kernel embedded operating system, including overview of inter-process communication, key techniques of designing piping routines such as getting i-node for piping, creating pipe, reading and writing pipe, and terminating pipe, etc. At the final, the paper provides a demo example to show the effect. Based on the piping routines described in this paper, more powerful shell interpreter with redirecting and piping functionalities as well as other shell commands analogous to that of embedded Linux can be implemented.

This paper describes the design and implementation of Web based secure embedded system, including tiny secure Web server, embedded system-based CGI library, and utilities for security, such as CAPTCHA program and mail sending program. The entire system is designed in C by the author of this paper on Linux platform with GNU tool chain. A Web based secure embedded application demo system is also designed to show the architecture and running effect. On the premise of implementing essential functions, the scale of the system is designed as small as possible therefore it is suitable not only for embedded Linux development on Web based applications but also for embedded system course teaching in colleges and universities. By some further extensions, it can also be used on development of general Web based MIS.

Spi Interface

SPI (Serial Peripheral Interface) is a full-duplex serial communication interface bus. Now, many devices adopt SPI. However, in many other aspects, microcontroller and microprocessor have no SPI interface, data transmission is inconvenient. With the development of FPGA technology, the problem can be solved absolutely by the I/O port of FPGA. In this paper, after introducing the principle of SPI, we designed SPI interface with FPGA and implemented the communication between SPI interface and the device of CRG20 which has a SPI interface. The algorithm of design SPI interface through FPGA is implemented with VHDL. The results of simulation in Quartus II and FPGA simulation are also described. The SPI bus interface modules fulfill the goal demanded.
