Abstract
Priority inversion is a phenomenon that a higher priority task is blocked by a lower priority task when they are sharing the same resource in a real time system based on the priority-driven scheduling.An improved priority inheritance protocol is proposed and the algorithm in μ C/OS-Ⅱ is also given.
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.
Application details are not available in the OpenAlex metadata.
