DDS is the software connectivity standard from OMG. Co-author of the DDS standard, RTI is dedicated to advancing open standards for real-time applications.
这个IP有两种工作模式:Rasterized模式和Standard模式,如下图所示,可通过Mode Of Operation进行设定。那么什么场景下用Rasterized模式?Rasterized模式和Standard模式又有什么区别呢? 我们先了解一下DDS的工作原理,如下图所示,DDS由两部分构成:相位累加器和相位波形转换器。前者根据给定的初始相位和相位步进值输出目标相位值,...
DDS中间件 DDS-The Proven Data Connectivity Standard for IoT API标准 包含了编程语言的相关标准: 用于DDS的ISO / IEC C ++ 2003语言PSM - 仅为DDS规范的以数据为中心的发布 - 订阅(DCPS)部分定义的C ++ API 用于DDS的Java 5语言PSM - 为DDS规范的以数据为中心的发布 - 订阅(DCPS)部分的定义Java API。
本次使用Vivado调用DDS的IP进行仿真,并尝试多种配置方式的区别,设计单通道信号发生器(固定频率)、Verilog查表法实现DDS、AM调制解调、DSB调制解调、可编程控制的信号发生器(调频调相)。 使用System parameters和Hardware parameters分别配置,对比**Standard Mode **标准模式和Rasterized Mode栅格模式的不同,对比不同时钟下...
Standard标准模式(常用),Rasterized栅格模式。两种情况下,输出的频率和频率分辨率、相位增量等参量的计算方式不同,具体参见Xilinx的PG141第14~18页。 Standard Mode 和 Rasterized Mode在实现指定频率、幅度的信号时,输出没有太大的差别,两者均能满足要求,一般使用Standard配置方便。
DDS中间件(图片来源DDS-The Proven Data Connectivity Standard for IoT) DDS发布订阅模型DCPS 讲具体协议之前,我们先熟悉下几个专有名词: Domain:代表一个通信平面,由Domain ID唯一标识,只有在同一个域内的通信实体才可以通信;如果考虑车内通信,可以只划分1个Domain,也可以按照交互规则或其他规则,定义多个Domain; ...
