摘要:
A system and method for reducing power consumption in a reconfigurable integrated circuit. Some embodiments provide placement and routing programs that reduce the number of bits to be reconfigured. Some embodiments provide placement and routing programs that increase the number of groups of circuits that do not need reconfiguration at some times. Some embodiments include circuits that selectively block reconfiguration.

An integrated circuit (“IC”) having configurable logic circuits for configurably performing multiple different logic operations based on configuration data is provided. The IC includes a row of the configurable logic circuits and multiple configuration retrieval circuits for providing configuration bits to the row of configurable logic circuits. The IC also includes a row configuration controller for forcing the multiple configuration retrieval circuits to output a particular configuration value based on a user signal that is received at runtime.

Some embodiments provide a method that identifies a first physical design solution for positioning several configurable operations on several reconfigurable circuits of an integrated circuit (IC). The method identifies a second physical design solution for positioning the configurable operations on the configurable circuits. One of the identified physical design solutions has one reconfigurable circuit perform a particular configurable operation in at least two reconfiguration cycles while the other identified solution does not have one reconfigurable circuit perform the particular configurable operation in two reconfiguration cycles. The method costs the first and second physical design solutions. The method selects one of the two physical design solutions based on the costs.

Some embodiments provide a method of designing a configurable integrated circuit (“IC”) with several configurable circuits. The method receives a design having several sets of operations for the configurable circuits to perform in different operational cycles. For at least a first set of operations that has a start operation and an end operation, the method assigns a particular operation in the first set to a first operational cycle based at least partially on the position of the particular operation with respect to the start and end operations.

Some embodiments of the invention provide a configurable integrated circuit (IC). The IC includes a logic circuit for receiving input data sets and configuration data sets and performing several functions on the input data sets. Each configuration data set specifies a particular function that the logic circuit has to perform on the input data set. The IC also includes a connection circuit for supplying sets of the configuration data to the logic circuit at a particular rate for at least a particular time period. At least two supplied configuration data sets are different and configure the logic circuit to perform two different functions on the input data.

The present invention introduces methods, systems, and architectures for routing clock signals in an integrated circuit layout. The introduced clock signal clock signal structures are rendered with non Manhattan routing. In a first embodiment, the traditional recursive H clock signal structure is rendered after transforming the coordinates system such that a rotated recursive H clock signal structure is rendered. In another embodiment, a recursive Y structure is used to create a clock signal structure. The recursive Y structure may also be implemented in a rotated alignment. For clock signal redundancy, non Manhattan wiring may be used to create a clock signal mesh network.

Some embodiments of the invention provide an integrated circuit (“IC”) that includes numerous configurable nodes arranged in an array having several rows and columns. In some embodiments, the configurable nodes include a first group of configurable aligned along a particular direction and a second group of configurable nodes aligned along a different direction. The IC also includes a set of direct offset turn connections arranged across the node array in a repetitive nested architecture. Each direct offset turn connection connects a node from the first group of configurable nodes to a node from the second group of configurable nodes. Each direct offset turn connection includes at least two wire segments that are arranged in at least two different directions and intersect to define a turn. No direct offset turn connection overlaps with another direct offset turn connection.
