术语 | mapped memory |
释义 | mapped memory 映象存储器;[映象记忆器] Memory that is divided into segments, or pages, each located separately in (mapped into) physical storage. Mapping translates the 16-bit addresses used with LSI-11 processors into a physical memory space of 18- or 22-bit address size. With the LSI-11/23, up to the equivalent of four 64K- byte virtual address spaces can be mapped into non-contiguous 8K-byte segments (18-bitmode) or 64 different spaces (22-bit mode). 分割为多个段或多个页面的存储器,其 每一个段或页面都独立地位于(映象到)物理存储体中,映象将LSI-11处理器使用的16位 地址转换为18位或22位的物理存储空间。在LSI-11/23情况下,最大相当于4个64K字节的 虚地址空间可映象为非连续的8K字节段(18位方式),或64个不同的空间(22位方式)。 |
