摘要
当前,测控系统正朝着高智能化、高实时性方面发展,基于此提出了一种以DSP为核心,并利用了双口RAM的数据采集处理系统,说明了其硬件连线方案.当ADC和DSP同时对双口RAM同一地址进行访问时,不发生冲突是系统设计成功与否的关键,详细给出了解决冲突的办法及相应的软件设计方法.系统构成合理,具有实际应用价值.
A data-acquisition system was proposed based on the DSP and the dual-port RAM, and the scheme of hardware wiring was brought forward. Whether the conflict takes place when the dual-RAM was accessed by ADC and DSP simultaneously was the crucial problem of the design of the system. The hardware arbitration was discussed particularly and the method of the design of software was given. The configuration of system is reasonable and it is useful in practice.
