摘要
A computer system includes a computer address modification system that is advantageously coupled in a bus network to selectively translate memory address data in 16K blocks and provide DMA page addresses which may match the 16K memory address blocks. The modification system includes a mapping RAM selectively providing translated addresses to enable addresses in a 1 megabyte address space to be selectively mapped to a 16 megabyte extended address space. The modification system also includes a page register storing for each addressable 16K block of data for each DMA channel a page address within the extended address space.
