Abstract

Improving processor performance pushes designers to look for every possible design alternative. Moreover, the need for embedded processing cores exhibiting low power consumption and reduced EM noise is leading to changes in system design. This trend has suggested the adoption of self-timed systems, whose energy and noise characteristics depend upon the processed data and the processing rate. In this paper, we explore the design space of first-in first-output queues, which are fundamental component in most recent proposals for asynchronous processors. Different strategies have been refined and evaluated using the handshake circuits methodology.
