架构行为

目的与范围

用途与范围

本单元定义普通程序计数器、陷阱程序计数器和指令束程序计数器视图的读写辅助函数。

概念与架构状态

计数器视图

ReadPC 和 ReadTPC 都返回 _PC。ReadBPC 返回独立的 _BPC 状态。

WritePC 和 WriteTPC 都替换 _PC，而 WriteBPC 替换 _BPC。

规则与交互

共享 PC 存储

PC 和 TPC 是同一个已存 Word 的两个访问名称；在本模型中它们不是独立计数器。BPC 与该共享存储相互独立。

边界与未定义范围

架构边界

这些辅助函数只定义存储访问。它们本身不定义指令顺序、对齐检查、陷阱进入、指令束完成或恢复资格。

使用示例

示例性视图示例

WriteTPC 存入一个对齐地址后，ReadPC 会观测到相同值，因为二者都使用 _PC。随后调用 WriteBPC 只改变 ReadBPC 返回的值。
