Enhanced GALS Techniques for Datapath Applications
Based on a previously reported request driven technique for Globally-Asynchronous Locally-Synchronous (GALS) circuits this paper presents two significant enhancements. Firstly, the previously required local ring oscillators are avoided. Instead, an external clock with arbitrary phase for each GALS block is used. Details of the required wrapper circuitry, the proposed design flow and performance...
متن کاملSystem integration by request-driven GALS design
A novel request-driven globally asynchronous locally synchronous (GALS) technique for the system integration of complex digital blocks is proposed. For this new GALS technique, an asynchronous wrapper compliant is developed and evaluated. This proposed GALS technique is applied to a baseband processor compatible with the wireless LAN standard IEEE 802.11a. The developed GALS baseband processor ...
متن کاملGALSification of IEEE 802.11a Baseband Processor
In this paper a Globally Asynchronous Locally Synchronous (GALS) implementation of a complex digital system is discussed. The deployed asynchronous wrappers are based on a novel request-driven technique with embedded time-out function. Each GALS block is fitted with a local clock generator for flushing the internal pipeline stages when there are no incoming requests. This request-driven techniq...

متن کاملLow power transformation of datapath architectures with cyclic SFGs
Datapath architectures exhibit a large amount of undesired switching (glitches) which does not contribute to the functionality but leads to increased power consumption. While glitch propagation can be effectively reduced by pipelining circuits with acyclic SFGs, this technique is not directly applicable if the circuit contains loops. The paper addresses this problem and discusses a methodology ...
