【摘要】 结合uClinux操作系统和S3C4510B的特点,设计了以中断方式实现的实时特征采集系统,通过开辟非实时程序与实时特征采集系统共享的存储区,将大大地提升纸币识别系统的并发处理能力。但是uClinux操作系统并不能完美地满足实时采集系统对实时性的要求。为了能使用功能强大并且免费的uClinux,有必要改进uClinux的中断延迟时间,提出了改进方法。经过改进后的uClinux可以满足要求。更多还原

【Abstract】 According to the Characteristic of uClinux and S3C4510B,designed a real-time data acquisition system which use interrupt.A memory area was set up which was shared by non-real time programs and this real-time data acquisition system,and it could greatly improve the ability of concurrent processing of this bill acceptor system.But the real time of uClinux could not perfectly meet the request of this real-time data acquisition system.In order to make use of uClinux which was free and had powerful function.It was necessary to improve its interrupt latency,and a method was brought forward.uClinux can meet the request of this real-time data acquisition system by using this method.更多还原
