| Abstract: | Based on the surveying, proceeding, analyzing research of electric signals of cerebral cortex, we present an application of embedded computer system that is based on ARM and μ C/os- Ⅱ real time operation system in Brain computer interface （BCI） communication. It gives out the design of high performance amplifier and the realization of software in this embedded computer system. We also talk about some disturb sources, and the way to decrease them. |
