Hybrid product term and look-up table-based programmable logic device with improved speed and area efficiency

摘要

A circuit comprising a programmable routing network, a logic array configured to generate a plurality of product terms in response to one or more of a plurality of input signals from said programmable routing network, a plurality of look-up tables each configured to receive a logical combination of at least two of said product terms and a plurality of macrocells each configured to generate an output in response to one or more of said look-up tables.
