Pedersen Bruce B, Cliff Richard G: Programmable logic array integrated circuits with enhanced output routing.. Altera, June 5, 1996: GB2295738-A (54 worldwide citation)

Flexibility in a programmable logic device is improved by allowing adjacent logic elements 12 in a logic array block to be cascaded selectively via AND gates 94. Further, an input carry signal 70a may be selected from either 70b an adjacent logic array block or 71a any other block via the local and ...
