查询词典 double-entry system

A relationship of the roughness parameters of diffusing surface strongly depend on the space correlation function of quasi—ideal imagine system has been confirmed and a new method for evaluating roughness has been proposed. In Chapter 4, the statistical properties of superposed dynamic speckle from a rotating diffuser have been investigated under double Gaussian—beam illumination.

同时，本章还证明了准理想外差成像系统动态散斑的空间相关与表面粗糙度参数之间有很强的依赖关系，在此基础上提出了一种新的工程表面粗糙的测量方法和计算机仿真的结果。

The characteristics of FIFO, double-port RAM and ping-pang cache structure were compared. The principle and features of ping-pang cache structure were discussed, and a real ping-pang cache structure was also given which consisted of high-speed, large capacity SRAM and FPGA. For a video processing system, this ping-pang cache structure is easy to interface with AD, DA and DSP.

文中比较了FIFO、双口RAM、乒乓缓存结构三种数据缓存电路的优缺点，讨论了乒乓缓冲控制器的结构和原理，并以高速、大容量的SRAM 以及FPGA器件为基础，设计了一种适应于高速DSP图像处理系统的乒乓缓存结构，其特点是速度快、所需器件少，易于与DSP器件接口。
