    摘要: Some embodiments of the invention provide a configurable integrated circuit (IC). The IC includes at least fifty configurable circuits arranged in an array having a plurality of rows and a plurality of columns. Each configurable circuit for configurably performing a set of operations. At least a first configurable circuit reconfigures at a first reconfiguration rate. The first configurable circuit performs a different operation each time the first configurable circuit is reconfigured. The reconfiguration of the first configurable circuit does not follow any sequential progression through the set of operations of the first configurable circuit.

    摘要: Provided is a method for estimating delay data comprising receiving an electronic representation of a source electronic design, estimating the criticality of connections which have not yet been placed across a boundary based on statistical data received from at least one other design and revising the design in a manner that biases the design towards a state in which connections with the highest criticality have their delays minimized. A statistical estimate is generated for uncut connections on a path in a partially placed source design comprising receiving at least one source design, partitioning the design, and generating statistical data corresponding to each type of partitioning cut.

    摘要: The invention concerns interface circuits for chip card readers. It consists of providing link connections between this circuit and the reader, these connections being identical to those established between the circuit and the chip card. An internal switch (102) in the circuit is used to link these connections together, or to a control register (101), which is internal to the circuit, and actuated by an additional control connection. With the invention, it is possible to limit the number of connections between the circuit and the reader and to control the circuit with a software interface which is identical to the control interface of a chip card.
