A generalized dictionary machine for VLSI. (English) Zbl 0555.68011

We show that a machine in which the processors are interconnected as a binary tree can support all the dictionary and priority queue operations as well as some other data queries. Everyone of the operations takes O(log n) steps where n is the number of keys present. A sequence of operations can be pipelined at a constant rate. In previous designs, either an operation required \(\Omega\) (log N) steps where N is the total capacity of the machine, i.e., the maximum number of keys that can be stored in it, or O(log n) performance was achieved at the expense of additional wires.
