مقایسه الگوریتم های زمان واقعی RTLinux و VxWorks
عنوان انگلیسی مقاله:
Comparison between scheduling algorithms in RTLinux and VxWorks
چکیده انگلیسی مقاله:
The scheduler decides wich one of the available tasks that will be next to be processed by the CPU. To make this decision the scheduler checks the priority levels of the scheduled tasks and apply a predefined schedule algorithm. This report will compare the scheduling algorithms in the real-time operating systems RTLinux and VxWorks and comes to the conclusion that the two compared systems are roughly equivalent in most uses in regards to this.
ترجمه چکیده مقاله به فارسی:
زمان بند تصمیم می گیرد که کدام یک از کارهای موجود ابتدا پردازش شوند. برای این تصمیم گیری، زمان بند اولویت کارهای زمان بندی شده را بررسی کرده و یگ الگوریتم زمان بندی از پیش تعیین شده را به کار می گیرد. این گزارش الگوریتم های زمان بندی واقعی را در سیستم عامل های زمان واقعی RTLinux و VxWorks را با هم مقایسه کرده و به این نتیجه می رسد که دو روش تقریبا در عمده کاربردهای مربوطه یکسان عمل می کنند.
