Abstract
Porting Embedded Linux kernel 2.4 and 2.6 to ARM9 Based Embedded Systems to compare the current consumption were experimental studied. Using the Linux 2.6 as operation system can save up to 35% power consumption while idle and about 20% while playing MP3 or MPEG. The current consumption showed no significant difference for the system using the Linux 2.4 while playing or leaving idle. A system using the Linux 2.6 operation systems can gain more energy benefits than that using Linux 2.4.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
