[Embeded-SCM Develop] fifov1

Description: FIFO（先进先出队列）通常用于数据的缓存和用于容纳异步信号的频率或相位的差异。本FIFO的实现是利用 双口RAM 和读写地址产生模块来实现的.FIFO的接口信号包括异步的写时钟（wr_clk）和读时钟（rd_clk）、 与写时钟同步的写有效（wren）和写数据（wr_data） 、与读时钟同步的读有效（rden）和读数据（rd_data） 为了实现正确的读写和避免FIFO的上溢或下溢，给出与读时钟和写时钟分别同步的FIFO的空标志（empty）和 满标志（full）以禁止读写操作。-FIFO (FIFO queue) is usually used for data caching and asynchronous signal used to accommodate the frequency or phase differences. The realization of this FIFO is to use dual-port RAM and to read and write address generator module achieved. FIFO interface signals, including asynchronous write clock (wr_clk) and read clock (rd_clk), and write effectively write clock synchronization (wren) and write data (wr_data), clock synchronization and time effective reading (rden) and read data (rd_data) in order to realize the right to read and write and to avoid FIFO overflow or the underflow, is given with the time clock and write clock synchronization FIFO respectively empty signs (empty) and full logo (full) to prohibit the read and write operations.

Description: 针对主控制板上存储器(SRAM) 存储的数据量小和最高频率低的情况,提出了基于SDR Sdram(同步动态RAM) 作为主存储器的LED 显示系统的研究。在实验中,使用了现场可编程门阵列( FPGA) 来实现各模块的逻辑功能。最终实现了对L ED 显示屏的控制,并且一块主控制板最大限度的控制了256 ×128 个像素点,基于相同条件,比静态内存控制的面积大了一倍,验证了动态内存核[7 ]的实用性。-For the main control board memory (SRAM) a small amount of stored data and the highest frequency of low, based on SDR Sdram (Synchronous Dynamic RAM) as the main memory of the LED display systems. In the experiment, the use of field programmable gate array (FPGA) to realize the logic function of each module. The eventual realization of L ED display control, and a master control panel to maximize the control of the 256 × 128 pixels point, based on the same conditions than the static memory control area has doubled, to verify the dynamic memory of nuclear [7 ] the practicality.

[VHDL-FPGA-Verilog] VHDL

Description: 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信号启动所选通道RAM中数值的显示过程。数值顺次显示一遍后显示结束，可以重新设定SEL的值选择下一个通道。模块数据线为8位，显示器件为4个8段LED。 7.数据采集模式如下：单通道采集（由SEL信号选择通道），多通道顺次采集（当前通道采满后转入下一通道），多通道并行采集（每通道依次采集一个数据）。模式由控制信号MODE选择，采集数据的总个数由NUM_COLLECT给出。 8.数据采集过程中不能读取，数据读取过程中不能采集-err

Description: 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 phase and frequency offset between different clock domain in communication area .In this paper, an FIFO module is designed using Gray convert technology and dual-port ram , which realizing scatheless transmit between different clock domain. The advances of Gray (Only one bit changes between neighboring two clock ) improves the reliability and anti-jamming capability of the system. And the system can work normally in the bad condition which the phase and frequency offset target to 300PPM. It is proved by work that the FIFO module can fulfill the demands of real-time of data transmitting system, and the module is powerful enough for more data process in the future.
