Implementation of Linux Optimization Technique for ARM Based System on Chip

Abstract

Abstract Applications of an embedded system have been expanded throughout the years. It is usually observed in the digital consumer market where cell phones are replaced by smart phones and internet tablets. More functionality is brought into one single purpose system for giving the enhanced services to the users. The Linux Kernel based operating system is used in most of these electronic devices. The biggest protests about Linux are the size and speed at which it boots. The users expect these devices to have fast boot up time and a small amount of memory. In multiple real-time systems, many Linux versions are used that need a large level of accessibility and negligible downtime when updating systems. This results in advancing Linux boot time and size optimization. The objective of this paper is to keep the researchers up to date about Linux Optimization techniques. First of all, this paper survey the various boot time optimization techniques and size reduction techniques with respect to conventional Linux system. It then implements the efficient size optimization technique for ARM based Raspberry Pi board. The findings reveal that the operating system image builds after size optimization technique is 25% lighter in size than original image and boot-up time diminishes by half.
