Paper Title
Comprehensive Survey of FPGA Architectures: Past, Present and Future
Abstract
Rapid developments in Field Programmable Gate Array (FPGA) technologies have led to introducing various
types of complex chips over the past years from various vendors with different programming technologies; such as Static
RAM (SRAM), Anti-fuse and Flash. Hence, today's cutting-edge FPGAs are highly complex in design while being
manufacture don extremely narrow geometries using advanced transistor processing technologies. As a result, this increased
complexity of currently-available FPGAs calls for anup-to-date survey. This is the aim of this paper where the authors
present a brief overview of these available FPGA architectures. This is achieved by following a systematic flow starting
from standard FPGAs to today’s cutting-edge hybrid FPGA architectures. Also, this paper includes a brief introduction to the
fundamental elements of reconfigurable logic. Underlying FPGA switch programming technologies and routing architectures
are also covered. This is followed by a discussion of future FPGA trends. This paper concludes how FPGAs can dominate
5G wireless, adaptive and smart data centers and Artificial Intelligence(AI) inference by outperforming conventional
techniques.
