MIZI Research, Inc.发布的嵌入式Linux内核源码，现在的版本是是2.4.18-rmk7-pxa1-mz5。其中包含了很多常用硬件驱动，如CS8900、UDA1341等。 这是为一款用SAMSUNG公司S3C2410A芯片为处理器的系统配置的内核，可支持 640*480 TFT、Audio、LAN、RS-232、USB等接口。(MIZI Research, Inc. Release of embedded Linux kernel source, the current version is over 2.4.18- rmk7- pxa1- mz5. It covers a lot of common hardware drivers, such as CS8900, UDA1341 so. This is a new company with Samsung S3C2410A chip processor for the system configuration of the kernel, can support 640* 480 TFT, Audio, LAN, RS-232, USB interface.)

该源码采用嵌入式linux中input子系统框架写的ds18b20温度传感器驱动程序，里面也有测试程序，在S5PV210的arm板上经测试，可以直接编译使用
