為了降低開發(fā)成本，縮短開發(fā)周期，提高系統(tǒng)性能和穩(wěn)定性，本文采用嵌入式X86 CPU
和嵌入式ARM處理器上下位機的硬件結(jié)構(gòu)形式。按照Linux操作系統(tǒng)下設備驅(qū)動程序開發(fā)的一般步驟和基本結(jié)構(gòu)，采用模塊化開發(fā)的基本思路，對基于ARM處理器嵌入式數(shù)控系統(tǒng)運動控制卡驅(qū)動程序進行優(yōu)化開發(fā)，保證了嵌入式運動控制卡在Linux環(huán)境下的高可靠性工作。本文深入研究了嵌入式數(shù)控系統(tǒng)硬件設計、硬件選型和軟件架構(gòu)設計與實現(xiàn)。

Abstract: In order to reduce development costs and shorten the development cycle, improve
system performance and stability， this paper use embedded X86 CPU and embedded ARM
processor machine in the form of hardware.According to the structure and development step of device drive program deeply under Linux OS,with the idea of modularize,the driver of motion control card based on ARM CPU is developed,which assure the reliable work of embedded motion control card under Linux. In this paper, in-depth study of the NC embedded systems hardware design, selection of hardware and software architecture design and implementation.
