A Framework for Architecture-Level Exploration of 3-D FPGA Platforms

Interconnection structures in FPGAs increasingly contribute more to the delay and power consumption. Three-dimensional (3-D) chip stacking is touted as the silver bullet technology that can keep Moore's momentum and fuel the next wave of consumer electronics products. However, the benefits of such a technology have not been sufficiently explored yet. This paper introduces a novel 3-D FPGA, where logic, memory and I/O resources are assigned to different layers. Experimental results prove the efficiency of our architecture for a wide range of application domains, since we achieve average performance improvement and power saving of 30% and 10%, respectively.
