基于FPGA的pci总线接口设计。。。。。。。。。。。。。(FPGA-based PCI bus interface design)

LPC4357开发板采用ARM的Cortex-M4微控制器LPC4357。内置一个ARM Cortex-M0协处理，CPU运行频率高达204MHz，片内集成1MB Flash和36KB SRAM。开发板采用独立核心板设计，核心板集成64MB SDRAM、128MB NAND-Flash、4MB SPI-Flash。核心板上的摄像头接口可直接连接各种型号的摄像头，两侧160P排针接口引出了除EMC总线外的LPC4357芯片所有功能管脚。 开发板提供丰富的外设接口，包括以太网、液晶屏、摄像头、USB-Host、USB-OTG、SD卡、RS232、RS485、CAN、耳机、麦克风、温度传感器、AD/DA、JTAG仿真器等。此外，开发板提供一个14P扩展接口，包括1路UART、1路SPI、1路I2C、4个IO、3.3V、5V，可以很方便的扩展自己的外围电路。(DS-LPC4357 development board using the Cortex-M4 microcontroller LPC4357 ARM s. A built-in ARM Cortex-M0 co-processor, CPU operating frequency up to 204MHz, 1MB Flash and 136KB SRAM integrated on chip. Development board using an independent core board design, the core board integrates 64MB SDRAM, 128MB NAND-Flash, 4MB SPI-Flash. Camera core board interface can be directly connected to various types of cameras, both sides 160P pin interface leads to the outside of the bus in addition to EMC LPC4357 chip all the functions of the pins. Development board provides a rich set of peripheral interfaces, including Ethernet, LCD screen, camera, USB-Host, USB-OTG, SD card, RS232, RS485, CAN, headphone, microphone, temperature sensor, AD/DA, JTAG emulator, etc. . In addition, the development board provides a 14P expansion interfaces, including one-way UART, 1 road SPI, 1 channel I2C, 4 个 IO, 3.3V, 5V, can easily expand their peripheral circuits.)
