An Energy-Efficient Architecture Template for Wireless Communication Systems
Project summary:
Mobile communication devices are rapidly evolving. Simple cellular phones are being replaced with modern smartphones, which enable permanent Internet connectivity and many new applications. However, this trend towards more powerful smartphones increases the design challenge enormously. Future designs must offer higher data transfer rates, higher programmability, higher design reusability, better compatibility for advanced technologies and consume less energy than current ones. Nevertheless, many ofthese requirements are clearly conflicting. Since state-of-the-art design approaches focus only on the optimization of a few of these requirements (which was sufficient in the past), but not on all of them together,innovative design approaches are urgently needed.This thesis proposes an innovative design approach which targets implementations that can sufficiently fulfill the combined set of requirements (listed above). The core of the proposed approach, and the main contribution of this thesis, is the energy-efficient domain-specific instruction set processorarchitecture template for the wireless baseband domain. To prove the feasibility and the efficiency of the proposal, two important designs havebeen implemented in advanced process technologies. The implementations fulfill all requirements sufficiently and consume at least a factor 2-3 less energy than state-of-the-art programmable solutions. Thus, this thesis significantly contributes in enabling the design of future smartphones with better capabilities.
