Abstract:
To satisfy the growing demands of today’s information society, hardware solutions have to process complex algorithms at high data rates. The key enabler for the required computational power has been the great and continuous progress in CMOS technology. However, in digital circuits implemented in recent deep submicron CMOS technologies power consumption has become a major bottleneck.

This work explores the potential of improving the power efficiency of digital circuits using optimizations at the algorithmic and architectural level. To this end, the impact of the algorithm characteristics on architectural complexity is investigated and high-level, low-power design techniques are discussed. To demonstrate the effectiveness of the proposed methods power-efficient ASIC implementations solving the major challenges of the digital baseband in 2G, 3G and 4G cellular systems have been realized, with a focus on turbo decoding and channel equalization.
