摘要
介绍了在研制的儿童多动症治疗仪中S3C2410与TMS5402双机通讯的实现。TMS5402的HPI接口是一个8位的并行接口,与主设备或主处理器连接后除DSP可访问本身RAM区域外,主机S3C2410也可通过HPI接口实现对DSP双访问RAM的访问,从而实现与DSP的通信。ARM芯片结合linux操作系统可作为仪器通用平台,再结合DSP芯片实现算法,可满足绝大部分检测应用场合的需求。
Introduce inter-communications between S3C2410 and TMS5402 on ADHD therapeutic instrument. Its HPI is an 8-bit parallel port in TMS5402, while S3C2410 links with host PC and host processor, meanwhile accesses RAM. S3C2410 can also access dual access DARAM in DSP by HPI, thus realize communications with TMS5402. ARM processor with linux operation system can be a platform for instrument development. The design based on DSP and ARM coordinate application can be generally used in detection instrument.
