Abstract


Field instruments and business equipment embedded technology is the development trend of the enterprise monitoring system. Combined embedded technology and Internet technology, making the entire industrial network easier and seamless connectivity over the Internet; most enterprises control network via a dedicated line for data communication, and the penetration of the Internet technology, the remote control of embedded devices and management is no longer need a dedicated communication line, the transmission of information is no longer limited to the data information. On the other hand, the MicroBlaze Xilinx FPGA-based microprocessor IP core, and other peripheral IP cores, can complete programmable system-on-chip design. The MicroBlaze 32-bit soft processing cores running speed of 150 MHz, up to 100 D-MIPS performance. When its integration with the Internet and can be embedded Internet communication interface and easily complete the remote transmission of data collection. To this end, a useful exploration. First, based on the MicroBlaze soft-core processor and Xilinx's FPGA chip technology, as well as the data via Ethernet for remote transmission study. Complete the system functions required to generate a variety of embedded function modules, which use the Xilinx EDK tools MicroBlaze soft-core processor embedded in the Spartan-3E and generate embedded on-chip peripheral bus interface to handle This machine bus interface, memory controller, local memory, data cache and instruction cache, UART, interrupt controller, timer, I2C interface, an Ethernet interface, or to take advantage of EDK provides a wealth of IP resources, build a relatively complete embedded microprocessor systems. As a hardware platform for the normal operation of the system can seriously study the principle of the uClinux embedded operating system, master configuration and application method for generating complete programming uClinux operating system, network applications design, data transfer program design, implementation transplant MicroBlaze soft-core processor. The PC can receive and display network data, as well as the received data processing, storage and forwarding, PC terminal application software developed under the Linux operating system, and ultimately the overall function of the system. Online tests carried out by the system, the design and implementation of signal reception and transmission functions, meeting the target.
