基于DSP和FPGA的通信控制系统的设计

【摘要】 通信控制系统是整机系统中必不可少的一部分,该系统的设计主要是以DSP和FPGA作为硬件资源,利用DSP的高速性实时的实现与上位机和各个分机之间的数据通信,利用FPGA的灵活性实现地址译码和信号幅度的计算,并且可以根据信号幅度控制信号的衰减,16c550芯片和HPI为该系统提供了外部通信接口。本系统在大多数整机系统中具有通用性。更多还原

【Abstract】 Communication and control system is an essential part of the whole enginery system,this system is designed mainly based on hardware resources of DSP&FPGA.For the characteristics of high-speed,the DSP could achieve real-time data communications with the PC and any extension.For the Flexibility, the FPGA could achieve address decoding and the calculation of signal amplitude and then control the signal attenuation base on the amplitude.The chip of 16c550 and the HPI provide an external communication interface for this system.In most of the whole enginery system, this system is universal.更多还原
