如何在kristen中创建多个通用FPGA结构？
How do I create multiple common FPGA structures in kristen?
我正在尝试使用 Kristen 生成 FPGA 主机 verilog 和一个 C++ 源软件来访问 FPGA 主机。问题是我有几个通用寄存器块用于控制几个神经营养处理器实例（可参数化），我不想只复制 XML 定义。有没有办法复制定义文件的一部分？有没有办法给它提供一个参数来让它复制？所以如果我增加 NMP 实例，我会得到更多的 SW 主机实例？
具体来说，我想为每个 NMP 实例复制 nmp 寄存器。但是我只想要一份版本，DDR和核心寄存器。
我不想做的是将这些行复制 1000 份并给它们单独命名。

所以您可能需要稍微改变一下。不完全知道你想要如何组织，我建议制作两个单独的模块。其中一个模块是您的设备和核心内容的单个实例，第二个模块是您的 nmp 内容并被复制 X 次。
无法向 XML 提供定义或参数以从外部控制复制，但您可以在 XML 中放置一个固定数字以引起复制。这里有一些权衡。我认为一种方式比另一种方式更昂贵，但您可以尝试一下，看看会发生什么。
我把它分成下面两个模块，并添加一个 "duplicate" 属性。我认为这将在 verilog 中随意创建 1000 个模块，并为它们分配名称，如 nmp1、nmp2 ... nmp1000。我认为这很容易做到，但它会花费你大量的微处理器接口逻辑。

稍微复杂一点的事情是将副本放在每个寄存器和存储器本身上。我认为这会节省一些资源，但对于 1000 个实例来说仍然会有很多逻辑。
