Abstract
Some embodiments provide a configurable IC that includes several configurable logic circuits, where the logic circuits include several sets of associated configurable logic circuits. For each several sets of associated configurable logic circuits, the reconfigurable IC also includes a carry circuit for performing up to N carry operations sequentially, wherein N is greater than two.
Claims21
1-20. (canceled)
An integrated circuit (IC) comprising:
- a plurality of configuration data storage elements for storing a plurality of configuration data sets;
- and
- a region comprising:
- an N×M arrangement of configurable logic circuits of a particular type,
- wherein N and M are integer values that are greater than 10,
- wherein each configurable logic circuit is for performing one of a plurality of operations based on one of the plurality of configuration data sets,
- wherein at least one of the plurality of operations is a mathematical operation that produces propagate and generate signals for performing a larger mathematical operation;
- and
- a direct connection between a first configurable logic circuit in said arrangement and a second configurable logic circuit in said arrangement, wherein the first configurable logic circuit and the second configurable logic circuit are not vertically or horizontally aligned and do not neighbor each other.
