Abstract: A system and method for mapping an address space to a non-power-of-two number of memory channels. Addresses are translated and interleaved to the memory channels such that each memory channel has an equal amount of mapped address space. The address space is partitioned into two regions, and a first translation function is used for memory requests targeting the first region and a second translation function is used for memory requests targeting the second region. The first translation function is based on a first set of address bits and the second translation function is based on a second set of address bits.

Abstract translation: 一种用于将地址空间映射到非功率数量的存储器通道的系统和方法。 地址被转换并交错到存储器通道，使得每个存储器通道具有相等量的映射地址空间。 地址空间被划分成两个区域，并且第一翻译函数用于针对第一区域的存储器请求，并且第二翻译函数用于针对第二区域的存储器请求。 第一翻译函数基于第一组地址位，第二翻译函数基于第二组地址位。
