The design of a new FPGA architecture

Abstract

A new Field Programmable Gate Array (FPGA) architecture is described. This architecture includes a number of novel features not found in currently available FPGAs. It is believed to offer a significantly improved logic density in some common applications. This paper describes the development of the FPGA and looks at the mapping onto it of some interesting application circuit elements. The design is discussed in approximately chronological order which allows us to explain other options which were considered and rejected during the development process.
