NXP iMX8M Plus 雙網(wǎng)口性能測(cè)試

By Toradex胡珊逢

Verdin iMX8M Plus?是?Toradex?采用?NXP?最新的?i.MX 8M Plus?處理器的計(jì)算機(jī)模塊，其具有?4x Cortex-A53?和?Cortex-M7?核心，支持神經(jīng)網(wǎng)絡(luò)加速運(yùn)算的?NPU，H.265?硬件編碼，CAN FD?，以及雙路千兆以太網(wǎng)。配合?Verdin?開發(fā)板，用戶可以直接測(cè)試兩路以太網(wǎng)。文章將對(duì)網(wǎng)絡(luò)性能做簡(jiǎn)要的測(cè)試。


使用?Toradex Easy Installer?安裝?Linux BSP v5.3.0，?默認(rèn)的配置已經(jīng)支持兩路千兆以太網(wǎng)。因此安裝完成重啟后即可看到兩個(gè)網(wǎng)絡(luò)接口。
