System Generator 是高性能、高效的DSP算法建模工具,是DSP算法与FPGA的桥梁[7-8]。其作用如图1所示,可在Matlab/Simulink环境下对算法以及系统进行建模,并生成相应的工程,再调用ISE进行仿真、综合、实现。 Xilinx为System Generator提供了大量的信号处理模块(如FIR滤波器、FFT)、纠错算法、存储器以及数字逻辑功能,可以在...
1)打开Simulink库浏览器并建立一个新的Simulink模型,并保存为mydsp.mdl。 2)在浏览器中选择Xilinx DSP48模块,并将其拖拽到mydspmydelay.mdl;按照同样的方法添加边界定义模块以及System Generator标志模块。 3)为了测试DSP计算电路,添加Simulink标准库中的常数模块(Constant)和显示器(Display)模块。其中常数模块用于向DS...

15190 - 8.2 System Generator for DSP - An error reports "Undefined function or variable" during generation Description In all System Generator versions, up to and including v8.2, the following error occurs during code generation when a variable exists in the "stop time" of the simulation paramet...
Therefore, fronthaul links have very stringent timing requirements in order for the systems to function correctly. Fronthaul links are limited to 20 km transmission distance. Most of the fronthaul links are less than 10 km. CPRI links are all point-to-point links without a regular digital ...
1997, 2022 3 ObjectConnect function ObjectConnect is a set of control language (CL) commands that can be used to copy objects between systems easily and efficiently. The ObjectConnect commands use native save commands on the source system and native restore commands on the target system to copy...
