Abstract:

Code is becoming more and more complex in the application field of embedded systems. Some hardware resources such as memory and timer are limited. This and does not affect the time to process inte  rrupts under the limited hardware and the supporting circumstance without the operating system.

Key words: μCOS-Ⅱ, soft timer, task scheduler, timer precision, embedded system  , memory resource, operating system;soft timer resource
