然后会在MATLAB的代码编辑区打开默认的M文件: 可以看到该文件就是一个函数,因此只需要自行编辑一个function定义的函数即可在MCode中使用,创建一个新的M文件,然后输入如下所示的代码,其中: 函数名:state_machine 输入:din 输出:matched 以上的代码表示的是一个状态机(FSM—FiniteState Machine),有5个状态,能够检测连...
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...

(or more accurately, any function designated as a program entry point by the language front end callingexpand_main_function), it inserts a procedure call to__mainas the first executable code after the function prologue. The__mainfunction is defined in libgcc2.c and runs the global constructor...
并且可以生成HDL文件,或者网表,可以在ISE中进行调用。或者直接生成比特流下载文件。能够加快DSP系统的开发进度。 一、Black Box调用HDL代码 1、简介 但是System Generator提供了一个特性:可以通过black box这个block将其它HDL文件以黑盒的形式封装到System Generator设计中,在仿真时使用Simulink+Vivado Simulator(...
To get an idea of the type of calculations a DSP does and get an idea of how an analog circuit compares with a DSP system, one could compare the two systems in terms of a filter function. The familiar analog filter uses resistors, capacitors, inductors, amplifiers. It can be cheap and...

一旦定义了FPGA边界就可以通过Xilinx DSP模块集合来建立各种DSP设计,包括滤波器、存储器、算术运算器、逻辑和比特操作器等丰富资源,每个模块都有详细的工作频率和比特宽度定义。标准的Simulink模块不能在“Gateway In”和“Gateway Out”之间使用,但常用来产生测试数据以及对FPGA的输出数据进行处理和分析。下面给出一个简...
