1. An integrated circuit (“
- IC”
) comprising;
a plurality of configurable nodes arranged in an array; and
a plurality of direct connection schemes for the plurality of said nodes, wherein each direct connection scheme for a particular node specifies a set of direct connections between the particular node and a set of nodes, wherein at least two similar nodes have two different direct connection schemes, wherein two direct connection schemes are different if they have different arrangements of direct connections, and the difference in the arrangements of direct connections is not necessitated by an absence of nodes in the array of configurable nodes that would otherwise allow the direct connection schemes to be the same.

Abstract
Some embodiments provide an IC with a configurable node array that has (1) two similar nodes within the interior of the array, and (2) two different connection schemes. The first connection scheme specifies a set of connections between the first node and a set of nodes in the array, while the second connection scheme specifies a second set of connections between the second node and a set of nodes in the array. The two nodes cannot connect to any nodes on the boundary of the array with any connection that is specified in any connection scheme.

18. An electronic device comprising:
an integrated circuit (“
IC”
) comprising;a) a plurality of configurable nodes arranged in an array comprising first and second nodes that are similar to each other; b) a first direct connection scheme that specifies a first set of direct connections between the first node and a first set of nodes; and c) a second direct connection scheme that specifies a second set of direct connections between the second node and a second set of nodes, wherein the first and second sets of direct connections are different, wherein two direct connection schemes are different if they have different arrangements of direct connections, and the difference in the arrangements is not necessitated by an absence of nodes in the array that would otherwise allow the direct connection schemes to be the same. - View Dependent Claims (19, 20, 21, 22)
