摘要
文章提出并论证了在光传输设备中利用SPI总线替代并行地址数据总线的设计,利用SPI总线实现设备板卡间通信,极大地简化了设备的背板及各单元板的硬件设计,是一种简易、可靠、稳定的传输方式。
This paper presents and demonstrates the use of SPI bus instead of the parallel address data bus in the optical transmission equipment. The SPI bus is used to realize the communication between the devices boards, which greatly simplifies the hardware design of the backplane and the unit board, is a simple, reliable, stable transmission mode.
