VLSI-oriented asynchronous controller synthesis based on a flip-flop cell array structure

Abstract

Presents a new implementation method of asynchronous controllers based on a cell array structure. Two kinds of cells are used to map asynchronous circuits synthesized by one-hot code assignment into layout; a basic cell with a flip-flop memory and set-reset logic, and an extension cell with set-reset logic. The present method gives considerable area reduction compared with a PLA-like implementation.<>
