Abstract
Application, embedded computer-based technology, is one of today's fastest-growing,
most widely used, the most promising technologies. Embedded technology has been widely
used in industrial control, mobile communications, information appliances, medical
equipment, automotive electronics, aerospace and other fields.
In a variety of embedded processors, ARM advantages of small size, low-power, low-
cost, high-performance, get the support of many semiconductor manufacturers, achieved great
success in the field of embedded applications. Software, u C / OS is a free, open-source,
compact structure, can be deprived of a real-time operating system for real-time kernel, thus
frequent.
This paper studies the μC / OS-II in the S3c2440 chip transplant. This article by S3c2440
hardware and open source embedded real-time operating system μC / OS-II analysis, for
example, described to S3C2440 ARM9 on transplantation μC / OS-II to run multiple tasks to
illustrate with LCD transplant μC / OS-II strengths and weaknesses, as well as the transplant
should pay attention to the problem of understanding of the startup code, the parsing code
optimization.
Key words: embedded system; real-time; ARM9; μC / OS-II
