This white paper examines three categories of process characteristics, relates them to the internal structure of modern FPGAs, and then, in turn, looks at the impact the FPGAs have on the systems that employ them. In particular, a focus on the deployment of so-called FinFET transistors shows how Altera is exploiting Intel’s 14 nm Tri-Gate process to achieve a level of FPGA density, performance, and power efficiency not reachable at all on the planar FET roadmap.
