Galaxy Gals

GALS systems despite having well-known drawbacks such as non-mature design-flow, lack of testing methods and no well-established target application, may offer significant advantages like better EMI characteristics, power reduction and process variability mitigation. These advantages have been explored in detail with theoretical research and chip fabrication and measurements. In addition, a systematic evaluation of GALS methodology benefits in NoC design process is performed.
