Protected sleeping task’s cache against illegal calling from currently running task by designing and initiating the MPU in ARM s3c2410. Effectively enhanced the reliability of embedded system software. Then carried on the static analysis, complexity analysis, and graphical analysis for code in the project using the LDRA Testbed, figured out each of the test results, accurately assessed the reliability of the system we designed, and provided suggestions to optimize it.
