New CMOS VLSI Linear Self-Timed Architectures

Description

The implementation of digital signal processor circuits via self-timed techniques is currently a valid altemative to solve some problems encountered in synchronous VLSI circuits. However; a main difference between synchronous and asynchronous circuits is the hardware resources needed to implement asynchronous circuits. This communication presents four less-costly alternatives to a previously reported linear selftimed architecture, and their application in the design of FIFO memories. Furthermore, the integration and characterization in the laboratory of prototypes of these FIFOs are presented.
