摘要： Some embodiments provide a method of presenting virtual memory as narrower and deeper than a physical memory. The method receives a memory address location including a set of real memory address bits and a set of virtual memory position bits. The method retrieves an original memory word from a physical memory using the real memory address bits. The method shifts the original memory word by an amount determined by the virtual memory position bits by using a barrel shifter, creating a shifted memory word. The method reads a part of the shifted memory word.

摘要： Some embodiments provide a configurable IC that includes a configurable routing fabric with storage elements. In some embodiments, the routing fabric provides a communication pathway that routes signals to and from source and destination components. The routing fabric of some embodiments provides the ability to selectively store the signals passing through the routing fabric within the storage elements of the routing fabric. In this manner, a source or destination component continually performs operations (e.g., computational or routing) irrespective of whether a previous signal from or to such a component is stored within the routing fabric. The source and destination components include configurable logic circuits, configurable interconnect circuits, and various other circuits that receive or distribute signals throughout the configurable IC.

摘要： Some embodiments provide a reconfigurable IC that includes several sections. Each section includes several configurable circuits, each of which configurably performs a set of operations. Each section stores multiple configuration data sets for each configurable circuit. Each configuration data set for a particular configurable circuit specifies the operation that the particular configurable circuit has to perform from the circuit's set of operations, where the configurable circuits of at least two different sections change configuration data sets at two different reconfiguration rates.

摘要： Some embodiments of the invention provide a configurable IC that includes several configurable computational tiles and several memory tiles. These tiles are arranged in a particular tile arrangement. Each computational tile has a set of configurable logic circuits for configurably performing a plurality of computations and a set of configurable routing circuits. The routing circuits of the tiles configurably route signals between configurable logic circuits. The configurable IC also has several memory arrays for storing data on which the logic circuit perform computation. The memory arrays are embedded in the tile arrangement between two sets of memory tiles, where each set of memory tiles includes a set of routing circuits. In this IC, at least a first memory tile has the same set of configurable routing circuits as at least a second computational tile.

摘要： Some embodiments of the invention provide a configurable integrated circuit (IC) that has several configurable circuits for configurably performing different operations. During the operation of the IC, each particular configurable circuit performs a particular operation that is specified by a particular configuration data set for the particular configurable circuit. While the IC operates and a first set of configurable circuits performs a first set of operations, configuration data is loaded from the outside of the IC for configuring a second set of configurable circuits. In some embodiments, the configurable IC includes a configuration network for rapid loading configuration data in the IC from outside of the IC. In some of these embodiments, the configuration network is a pipelined network.
