چکیده
In this report, the possibilities of reducing EMI in GALS systems are investigated and presented. Based on the special software tool for EMI analysis, several different abstract models of GALS circuits have been designed in order to extract a realistic pausable clock behavior. Based on the clock behavior, we have been able to analyze using our tool the current profile of each modeled system, both in frequency and in time domain. The results have been compared with the synchronous counterparts including low EMI solutions. As a result, a reduction up to 25 dB can be achieved when applying a low-EMI GALS methodology in comparison to the synchronous designs. Keyword list: GALS, EMI, current profile

A Design Path for Design of GALS Based Communication Systems
The GALS (Globally Asynchronous Locally Synchronous) approach is highly suitable for implementation of communication systems. In this paper we describe an efficient design flow for GALS design based on commercial tools. As design example we have selected a digital FIR filter. It is a nontrivial task to develop an efficient design flow for GALS based systems because of the asynchronous parts. Bo...

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...
