VHDL
- 采用VHDL语言设计一个4通道的数据采集控制模块。系统的功能描述如下: 1.系统主时钟为100 MHz。 2.数据为16位-数据线上连续2次00FF后数据传输开始。 3.系统内部总线宽度为8位。 4.共有4个通道(ch1、ch2、ch3、ch4),每个通道配备100 Bytes的RAM,当存满数据后停止数据采集并且相应通道的状态位产生报警信号。 5.数据分为8位串行输出,输出时钟由外部数据读取电路给出。 6.具备显示模块驱动功能。由SEL信号设置显示的通道,DISPLAY

fpga.fifo
- 异步FIFO是用来适配不同时钟域之间的相位差和频率飘移的重要模块。本文设计的异步FIFO采用了格雷(GRAY)变换技术和双端口RAM实现了不同时钟域之间的数据无损传输。该结构利用了GRAY变换的特点,使得整个系统可靠性高和抗干扰能力强,系统可以工作在读写时钟频率漂移达到正负300PPM的恶劣环境。并且由于采用了模块化结构,使得系统具有良好的可扩充性。-Asynchronous FIFO is an important module which always used to absorb the
HardCamera
- The objective of this project is to create a driver for a camera module (we used the OV7620). After taking the image with the camera, the driver will store into the external asynchronous RAM, and then send it to the computer through a serial cable
RS232capture
- This approach, we feel, came very close to obtaining an image from the camera OV7620. Before we tried to capture a camera signal, we successfully transferred a test image from the FPGA s onboard RAM modules through RS232 to the PC program. This file
