Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.

是verilog例子。初级适用。包括了简单的例子。-example. The initial application. Including a simple example.

图像采集 VGA输出 图像的边缘 ov7670(V image acquisition VGA output image edge)

应用背景FPGA原型的VHDL例子提供一系列清晰，易于遵循的快速代码开发模板；大量的实际例子来说明和强化的概念和设计技术；现实可实施的项目和测试在Xilinx原型板；深入探索和Xilinx PicoBlaze软核微处理器。关键技术本书采用“做中学”介绍VHDL和FPGA技术的概念和设计人员通过一系列的实验方法。

cordic 算法知道正弦和余弦值，求反正切，即角度。(The CORDIC algorithm knows sine and cosine values and asks for inverse tangent, that is, angle.)
