| Summary: | Compiler optimizations have been proven to be beneficial in improving
performance and efficiency of binary codes across different type of operating
systems. Improvement from optimization of program code during compilation are
obvious to the system performance, memory performance, disk access, energy
efficiency and nearly all aspect of the system. This is particularly attractive to an
embedded system where performance and efficiency are seriously considered. This
research focuses on implementing those proven compiler optimizations to the
development of an embedded operating system and studying the effect of such
implementation to the performance and efficiency of the system. This thesis outlines
the methods available to develop a custom operating based on the Linux kernel and
ways to implement such optimization during the compilation and development
process. Focusing on face recognition systems implemented on embedded Single
Board Computers, optimization effects to an embedded operating system are studied
through software and hardware perspective. From the software perspective; booting
performance, code execution performance and binary efficiency of different
prototypes developed with varying level of compiler optimization are tested and
examined. From hardware side; system memory footprint, current draw, power
consumption and energy usage of the different prototypes are tested and measured.
Results obtained in this thesis shows that compiler optimization are beneficial not
only when applied to the program code, but also have significant effects when
applied to the operating system. |
