verilog 温度控制命令

介绍了在数字语音通信中, 利用在系统可编程技术和复杂可编程逻辑器件CPLD, 实现了数字语音的复接和分接 对于其中的单稳态电路的数字化和数字锁相环提取位同步信号也进行了详细的设计说明。实际应用结果表明, 系统工作稳 定可靠, 设计是成功的。(Describes the digital voice communications, the use of in-system programmable technical and complex programmable logic device CPLD, to achieve the digital voice multiplexer and demultiplexer for the single steady state in which the digital circuit and digital phase locked loop extraction bit synchronization signals are also carried out a detailed design specification. The practical application results show that the system works stable and reliable design is successful.)

Actel 8051 Verilog core

使用matlab的simulink工具滤波器功能实现了FIR系数的计算，同时使用verilog hdl实现了功能仿真，通过调试在Xilinx的ZEDBOARD板子上实现了结果，使得FIR的应用得以在硬件上实现，调试和注解有写。

一个三分频verilog模块，可以用来学习基本结构。(A three points frequency verilog module can be used to study the basic structure.)

说明：  ? 熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。 ? 利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。 ? 利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。 ? 利用双线性插值方法实现对图像640×480到1024×768的放大操作。 ? 完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format. Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface. With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA. The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768. Complete the VGA display interface design.)
