FPGA在IRIG-B码源设计中的应用

FPGA is applied in the IRIG-B code Generator

Cyclone系列芯片是Altera公司推出的低价格、高容量的FPGA,内置M4K存储块,最大RAM可达288kb。IRIG-B码是标准时间码格式之一,广泛的应用于靶场时间信息的传递和各系统的时间同步。利用Cyclone的内置M4K存储块,结合MSP430单片机设计的IRIG-B码时钟源,实现了系统的小型化、模块化。结果表明:该系统运行稳定,调试方便,克服了硬件电路复杂的缺点。

Altera’s low-cost、high-content Cyclone series have M4K memory blocks,M4K memory blocks provide deeper and wider memory functions.Up to 288Kbits of RAM. IRIG-B code is one of the standard time code format , used for time information transfer and time synchronization between different ranges in the shooting range system.IRIG-B code generator base on M4K memory blocks and MSP430 achieved miniaturization and modularization. The results demonstrate that the system runs steadily,debug simply and hurdie the disadvantage of hardware circuit complexity.
