Abstract | As integrated circuits become increasingly complex, the ability to make post-fabrication changes will become more important and attractive. This ability can be realized using programmable logic cores. Currently, such cores are available from vendors in the form of a "hard" layout. Previous work has suggested an alternative approach: vendors supply a synthesizable version of their programmable logic core and the integrated circuit designer synthesizes the programmable logic fabric using standard cells. This paper presents a new family of architectures for these synthesizable cores; unlike previous architectures which were based on lookup-tables, the new family of architectures is based on a collection of product-term arrays. Compared to lookup-table based architectures, the new architectures result in density improvements of 35% and speed improvements of 72% on standard benchmark circuits. |
