择要:NXP iMX8已经正式宣布,相较于之前NXP i.MX系列的主力产品iMX6,其机能有了大年夜幅提升,本文就针对收集接口对NXPiMX8和iMX6两款ARM处置惩罚器进行比较测试。

1). 简介

NXP iMX8已经正式宣布,相较于之前NXP i.MX系列的主力产品iMX6,其机能有了大年夜幅提升,本文就针对收集接口对NXPiMX8和iMX6两款ARM处置惩罚器进行比较测试。

本文演示所应用的ARM平台来自Toradex基于NXP iMX8 SoC的Apalis iMX8 ARM核心板和基于NXP iMX6Q SoC的Apalis iMX6 ARM核心板。

2). 筹备

a). Apalis iMX8QM ARM核心版共同Apalis Evaluation Board载板,Apalis iMX8QM安装Toradex V3.0b2 Linux demo image,同时连接调试串口UART1(载板X29)到开拓主机方便调试。更多关于Apalis iMX8共同Apalis Evaluation Board载板的阐明请参考Datasheet和开拓上手指南

b). Apalis iMX6Q ARM核心版共同Apalis Evaluation Board载板,Apalis iMX6Q安装Toradex V2.8 Linux demo image,同时连接调试串口UART1(载板X29)到开拓主机方便调试。更多关于Apalis iMX6共同Apalis Evaluation Board载板的阐明请参考Datasheet和开拓上手指南

c). Ubuntu linux PC主机, 用于分手和Apalis iMX8、Apalis iMX6进行收发测试。

d). 测试对象软件应用 iperf3 对象,Toradex Linux demo image里面已经默认集成,Ubuntu 系统(这里以18.04为例)要经由过程apt敕令来安装iperf3

----------------------

$ sudo apt update

$ sudo apt install iperf3

----------------------

e). 收集连接拓扑为Apalis iMX8QM、Apalis iMX6Q以及Ubuntu PC都经由过程千兆有线收集连接到同一个局域网。

3). TCP收集传输机能测试比较

5). 总结

本文比较测试了NXP iMX6和NXP iMX8处置惩罚器的收集机能,对付iMX6,因为这个Eratta的限定,400Mb/s阁下的机能也就把相符文档的描述,iMX8则在大年夜多半环境下能够靠近千兆带宽。
