基于FPGA的闪存XX29F系列读写装置的设计

针对机载电子设备电路板件大量使用各类XX29F系列存储器的现状,为满足对该系列存储器读写操作的需要,基于FPGA设计一款针对各类XX29F系列存储器的读写装置.在对该装置功能、设计方案进行系统诠释的基础上,给出装置各模块的硬件电路设计,并基于Verilog语言开发相应模块的软件代码,最后利用RS232串口,控制对装置读写数据与上位机软件进行通信.实验结果表明,该装置读写操作简单,性能稳定可靠,可应用于飞机各类含XX29F系列存储器板件修理与测试中.

Design of Am29F400B Operation Method Based on FPGA

In view of the current state that series of the XX29F memories are widely used in airborne electronic equipment circuit board,in order to meet the need for this series of memories read/write operation,a device based on FPGA is designed to read and write the series of all kinds of XX29F memories.Based on the interpretation of device''s function and project design in a systematic way,the hardware circuit designs of various function modules are provided and the software codes of corresponding modules based on Verilog language are compiled.Finally,RS232 is used to control the reading and writing of the device data and communicate with PC software.The experimental results show that the device''s reading and writing operation is simple,performance is stable and reliable.It can be applied to repair and test of all kinds of airborne PCB that uses XX29F series memory.
