释义 look-aside registers
旁视寄存器
A set of control unit registers that holds the virtual addresses and hardware addresses of all pages and/or segments in primary storage. Each time a page/segment is referenced by an executing process, aparallel search of the registers is made to determine whether or not the page/segment must be rolled in from secondary storage. The registers are searched by content (virtual addresses) and the process may thus be termed content addressing or associative addressing and the registers are a form of associative storage.
