| Descripción |
This paper describes the Altera Stratix II ™ logic and routing architecture. This architecture features a novel adaptive logic module (ALM) that is based on a 6-LUT, but can be partitioned into two smaller LUTs to efficiently implement circuits containing a range of LUT sizes that arises in conventional synthesis flows. This provides a performance increase of 15 % in the Stratix II architecture while reducing area by 2%. The ALM also includes a more powerful arithmetic structure that can perform two bits of arithmetic per ALM, and perform a sum of up to three inputs. The routing fabric adds a new set of fast inputs to the routing multiplexers for another 3 % improvement in performance, while other improvements in routing efficiency cause another 6 % reduction in area. These changes in combination with other circuit and architecture changes in Stratix II contribute 27 % of an overall 51 % performance improvement (including architecture and process improvement). The architecture changes reduce area by 10 % in the same process, and by 50 % after including process migration.
