Study on the Hardware Initialization of Embedded System

Abstract

An embedded system generally comprises of four parts (embedded microprocessor unit, peripheral hardware equipment, embedded operating system, and user application), and its core function is to complete the control of different equipments as well as necessary monitoring and management measures. Initialization is to set a variable as "default value", including system initialization, software initialization and hardware initialization. However, these three types of initialization are classified in accordance with different layers. This is studied in this paper.
