基于FPGA实现四选一选择器的设计
摘要
本文是基于FPGA的四选一选择器的设计:基于FPGA在数据选择方面的优势,把FPGA作为选择器的控制核心;主要研究如下:
软件部分——四选一选择器程序。针对数据选择器的设计,对FPGA进行了型号选择,使用VHDL语言在型号FLEX10K/20RC208-4上编写了四选一选择器的程序,通过使能端的控制,从而达到四选一的功能。
硬件部分——使用protel画出原理图并作出PCB板。本设计采用了单八路模拟开关CD4051,通过输入端的控制,选择一路信号,通过ADC0804模数转化,输出8路信号给FLEX10K/20RC208-4,经FLEX10K/20RC208-4处理后,接TCL7528后,将数字信号转换为模拟信号并输出。
本文通过软件和硬件的两个方面的设计,实现了四选一选择器的功能。

FPGA implementation based on four selected design of a selector
Abstrate
This article is based on a choice selection of four FPGA Design: FPGA-based data selection in the advantages of the FPGA as a selector control center; main research are as follows:
Software parts - 4 election a choice program. Design for data selection, model selection on the FPGA, using the VHDL language in the model FLEX10K/20RC208-4 four selected to write a program selector, by enabling the client to control, so as to achieve a function of four elections.
Hardware - protel schematic drawing and make a PCB board. This design uses a single eight-way analog switches CD4051, through the control input, select the way the signal, ADC0804 module through the transformation of the output signal 8 to FLEX10K/20RC208-4, by FLEX10K/20RC208-4 treatment, then TCL7528, will digital signal is converted to analog signals and output.
In this paper, two aspects of hardware and software design, implementation, choose one of four selector functions.
Keywords: FPGA ; VHDL ; ROTEL ; selector
