摘 要

可重用设计方法是以IP复用和IP设计为基础的一种有效的设计方法与先进的

设计理念，它将传统的停留在板级设计层面的嵌入式系统硬件设计提升到基于可

编程逻辑芯片上的系统级设计。可重用设计方法的引入大大缩短了基于可编程逻

辑器件的嵌入式系统设计周期，更为科研院所将独创的算法模型迅速转化为IP核，

加以推广应用和知识产权保护提供一个良好的途径，成为设计系统原型的首选方

式。

本文将可重用设计方法成功地应用到实际科研项目——基于FPGA及IP软核的

介质损耗数据采集系统。分析了可重用设计方法在嵌入式系统设计中的重要作用，

Abstract

Reuse methodology is an efficiency method and advanced idea of chip design,

which is based on reusing and design of IP core. It changes the focus of system design

from the board-level of embedded system hardware design to the chip-level of

programmable logic device based design. The use of reuse methodology does not only

decrease the cycle of designing the embedded system based on programmable logic

device, but also is a shortcut to transfer a algorithm to an IP core to be protected better

and able to be used in lots of fields for academy or research institute.

This thesis makes use of reuse methodology to research project——Dielectric loss

customization of FPGA and the software designing based on NiosⅡ was introduced

from both the system design and the function module design aspects. Then the

anti-jamming principle of hardware design was also simply described in the thesis. The

dielectric loss data collecting system based on FPGA and IP core was designed and

realized on the basis of above research triumphantly.

Keywords: Reuse methodology FPGA IP core Dielectric loss data collection
