你好，我已经把由收发器和触发器组成的togethera电路允许我通过8位GPIO总线将Raspberry Pi连接到5v逻辑1mhz 8位计算机。我可以从复古计算机读取/写入，但是由于Raspberry Pi限制和非常紧张的时序余量，我在1000万次写入中遇到大约5个错误。为了解决这个问题，我可以添加更多芯片并通过硬件做更多工作，这将使设计复杂化，或者我可以在CPLD上完成所有工作，我的朋友推荐给我他的XC9500XL，我需要学习Verilog。在我开始之前，我遇到的一个问题是：我能够使用此CPLD创建收发器吗？我需要能够在两个方向上驱动总线以进行读/写。我也正在读Samir Palnitkar的“Verilog HDL”第二版，所以任何适用于我的项目的阅读建议都将受到赞赏。提前谢谢了！安东尼以上来自于谷歌翻译以下为原文Hello, I've put together a circuit consisting of transceivers and flip-flops that allows me to interface a Raspberry Pi to a 5v-logic 1mhz 8-bit computer via an 8-bit GPIO bus. I am able to read/write from/to the retro computer but I am experiencing approximately 5 errors out of 10 million writes no matter what I do due to Raspberry Pi limitations and very tight timing margins. To fix this I can add more chips and do much more via hardware which will considerably complicate the design or I can do it all on a CPLD, and my friend recommended and gave me his XC9500XL which means I need to learn Verilog. One question I have before I go ahead is : am I able to create a transceiver using this CPLD? I need to be able to drive the bus in both directions for read/write purposes. I'm also reading the book "Verilog HDL" 2nd Ed by Samir Palnitkar so any additional reading recommendations applicable to my project would be appreciated. Many thanks in advance! Anthony
