Operating System is an important software in computer system. For personal and office use the
operating system is sufficient. However, to critical miss
ion applications such as
nuclear power plants and
braking system on the car (auto brak
ing system) which need a high level
of reliability, it requires operating
system which operates in real time. The study aims to assess the implementation of the Linux-based operating
system on a Single Board Computer (SBC) ARM-based, namely Pandaboard ES with the Dual-core ARM
Cortex-A9, TI OMAP 4460 type. Research was conducted by the method of implementation of the General
Purpose OS Ubuntu 12:04 OMAP4-armhf-RTOS and Linux 3.4.0-rt17 + on PandaBoard ES. Then research
compared the latency value of each OS on no-load and with full-load condition. The results obtained show the
maximum latency value of RTOS on full load condition is at 45 uS, much smaller than the maximum value of
GPOS at full-load at 17.712 uS. The lower value of latency demontrates that the RTOS has ability to run the
process in a certain period of time much better than the GPOS
