摘要
用特别设计的自动检索电路与一般存储器一起构成一个独立的硬件排序单元．其时间、空间复杂度均是Ｏ（Ｎ）．它既可以作为主ＣＰＵ的协处理器。
An independent hardware sorting unit is formed with a specially designed automatic re-trieval circuit and a few general-purpose memories. Each byte of the is written suc-cessively in the sorting unit with the corresponding mark bits. The bytes are then read outfrom the priority encoder circuit so that the sorting for tuples will be completed from thelowest to the highest byte of the

in turn. If the number of tuples to be sorted is nand that of bytes of the Keywords for each tuple is m,then the sorting time complexity willbe 2nm or 2N(N=nm),or O(N).The main hardware of the sorting unit is the general-pur-pose RAMs, in which there are
