架构行为

目的与范围

用途与范围

本单元提供可执行内存模型使用的有界字节地址访问层。它判断一个 Word 地址是否位于已配置模型内，并为有效地址提供字节读取与写入。

概念与架构状态

地址与存储概念

  • IsModelAddress 将 UInt(address) 与 PTO_MODEL_MEMORY_BYTES 比较。
  • ReadMemoryByte 返回转换后的模型索引在 _Memory 中保存的 Byte。
  • WriteMemoryByte 更新同一个按字节寻址的 _Memory 状态。
规则与交互

访问顺序

两个访问器都会先断言 IsModelAddress(address)，再把地址转换为 ModelAddress。因此调用方必须先建立模型范围有效性，随后才能观察或修改一个字节。

边界与未定义范围

模型边界

已配置的 _Memory 数组是可执行验证存储。它的大小限制当前模型实例；本页并不声称每个 PTO 实现都把该字节数作为其架构地址空间。

使用示例

示例性访问示例

本示例块只用于帮助阅读：先应用上文规则，再到规范 ASL 所有者中确认结果。它不会增加任何架构契约。

相关所有者

  • PTO-ARCH-STATE-DEFINEDNESS 提供本单元使用的状态基础。
  • 内存事件和指令访问所有者在这些字节辅助函数之上构建更高层行为。
