Abstract:
The adaptiveness of Field Programmable Gate Arrays is a key aspect in many mobile applications. Modern vehicles contain up to 100 ”Electronic Control Units” in order to im- plement all necessary functions for autonomous driving. Due to the limited power resources of mobile applications, an appro- priate implementation of power reduction measures is crucial for achieving an acceptable amount of power savings. However, effective power reduction mechanisms have to be applied to the backbone of each Field Programmable Gate Array: the look-up table. In this paper, we describe the implementation and comparison of various Static Random Access Memory cells and the related characteristics which are used as a benchmark. All Static Random Access Memory cells have been analyzed in order to evaluate feasible modifications for the sake of lowering leakage currents and modified for minimizing static and dynamic power consumption. The trade-off between low-power use cases, a fast response time and area considerations as well as yield after manufacturing has to be carefully analyzed. Therefore, further aspects like signal to noise ratio and area increase due to additional, required transistors are deliberated about whether the additional efforts delivers desired results. Since speed in terms of a high operating frequency is demanded by many applications, we analyze each design upon its capabilities to run at their maximum speed.
