1. Introduction of an Embedded system


1.1 Definition of an Embedded system

An embedded system is various type of computer system or computing device that performs a dedicated function and/or is designed for use with a specific embedded software application. Embedded systems may use a combination of ¡®Read-only¡¯ as well as with ¡®Read-Write¡¯ based operating system. But an embedded system is not usable as a commercially viable substitute for general-purpose computers or devices.

1.2 Definition of an Embedded OS

An embedded operating system is the software program that manages all the other programs in an embedded device after initial load of programs by a boot loader.
It normally guarantees a certain capability within a specified storage size and time constraint as well as with application programs. It also normally has small foot print including initial boot loader, OS kernel, required device drivers, file systems for the user data and so forth. It has very-likely structure of a normal operating system however mainly differentiated by some factors such as type of pre-installed device, functional limits, taking designed job only.

1.3 Linux as an Embedded OS

Embedded Linux is inherited from Linux that has been modified and upgraded by developers in Linux community to be fit as an embedded operating system. It is normally said that embedded Linux has advantages of ¡®portability¡¯, ¡®flexibility¡¯, ¡®lower cost¡¯ and ¡®development environments¡¯. That is why embedded Linux is nowadays widely using in embedded devices.

1.4 Introduction of the MIZI Linux

MIZI Linux¢â is an embedded Linux distribution which is specially designed for a smart handhelds and digital appliances. By the efforts of MIZI Research during several years MIZI Linux¢â distribution includes many of add-up values, software patches and development kit, and typical user applications for the target devices. MIZI Linux¢â has been installed following type of device especially;

The document is dedicated to introduce our distribution, MIZI Linux¢â v1.x (code name ¡®Linu@¡¯).
