好多嵌入式机型是不是只支持arm64-v8a内核的?Issuing time:2025-01-02 16:46 现在嵌入式开发软硬件开发,基本上都是64位架构了,arm64-v8a是比较新的架构,支持4G,8G,16G,32G以上内存,之前的armv7-a架构只支持到32位,硬件上也只支持到RK3128与RK3288的硬件架构,内存支持1GB,2GB,4GB。
从系统上来看,armv7-a支持的系统版本较低,一般是:安卓4.4,安卓5.1,安卓7.1等较低版本。参考板卡:DC_A128,如下图所示。 Arm-v8-a支持的系统版本较高,一般是安卓10,11,12,14,UBUNTU2004,2204,ROS2,甚至是国产化系统如:银河麒麟v10sp1与星光麒麟系统,还有鸿蒙4.12系统的板卡。参考板卡:DC_A588,如下图所示。
做嵌入式软硬件设备开发,新老客户可根据实际需求,灵活选择,单应用或者简单应用,armv7-a也能用,复杂应用或多应用等多媒体,AI算法开发,监控安防等应用开发,还是建议armv8-a。 Declaration: This article is originally created by the editor of Guangzhou Dingchang Electronics.
