Abstract

The invention provides an FPGA interconnect structure preferably included in an array of identical tiles. The interconnect structure includes both buffered and unbuffered interconnect lines. Some buffered interconnect lines are bidirectional, and others are unidirectional. A carefully selected mixture of unidirectional and bidirectional lines provides a balance of flexibility, silicon area, and performance.
