DSP和CPLD实现的地面实时数据处理系统

Real-time Data Processing System on the Ground Implemented with DSP and CPLD

用16位DSP和CPLD辅以一些外围器件实现了一个新型的实时数据接收、处理、转发系统。系统采用CPLD器件集成电路的全部控制功能,提高了芯片的工作速度、功耗特性、系统的可靠性。数据接收部分采用数据流状态机。解决了原系统数据延迟偏大的问题,并提高了数据发送的实时性和可靠性。

The new kind of real-time system which can receive,process and transmit data is implemented with 16 bits DSP and CPLD with some other periphery apparatus.It enhances the running-speed,reduces the power consuming and improves systemic dependability due to using CPLD to integrate the whole control functions of circuit.The receiving part adopts data-flow state machine.It mainly resolves the issue of too long data delay in old systems,and it also enhances real-time property and dependability of the system.
