    Abstract: A high-performance programmable logic architecture has embedded memory arranged at peripheries or edges of the integrated circuit. This enhances the performance of the programmable logic integrated circuit by shortening the lengths of the programmable interconnect (748). In a specific embodiment, the memory blocks (703,706) are organized in rows along the top and bottom edges of the integrated circuit. The logic elements can be directly programmable routed and connected to driver blocks of the logic blocks in adjacent rows and columns. This permits fast interconnection of signals without using the global programmable interconnect resources. Using similar direct programmable interconnections the logic blocks can directly programmable connect to the memory blocks without using the global programmable interconnect resources. The present invention also provides technique of flexibly combining or stitching multiple memories together to form memories of a desired size

    Abstract: A programmable logic device has many regions of programmable logic, together with relatively general-purpose, programmable, interconnection resources that can be used to make interconnections between virtually any of the logic regions. In addition, various types of more local interconnection resources are associated with each logic region for facilitating the making of interconnections between adjacent or nearby logic regions without the need to use the general-purpose interconnection resources for those interconnections. The local interconnection resources support flexible clustering of logic regions via relatively direct and therefore high-speed interconnections, preferably in both horizontal and vertical directions in the typically two-dimensional array of logic regions. The logic region clustering options provided by the local interconnection resources are preferably boundary-less or substantially boundary-less within the array of logic regions.

    Abstract: PROBLEM TO BE SOLVED: To provide an equalization circuit for appropriately compensating for attenuation caused by transmission media.SOLUTION: Data signals transmitted over transmission media suffer from attenuation caused by the transmission media. An equalization circuit (106) includes a plurality of stages (202) arranged in series to allow frequency responses of the stages (202) to be integrated together. Each stage (202) is programmable to insert a zero, thus causing the frequency response of the stage (202) to be increased in magnitude by 20 dB/decade. The frequency location of zero is also programmable to allow each stage (202) to contribute to a certain amount of a gain for a specific frequency. Each stage (202) is also programmable to determine the location of a pole for the reduction of high frequency noise and cross-talk cancellation.

    Abstract: PROBLEM TO BE SOLVED: To provide an equalization circuit for appropriately compensating for attenuation caused by transmission media.
    SOLUTION: Data signals transmitted over transmission media suffer from attenuation caused by the transmission media. Equalization circuitry (106) may include a plurality of stages (202) arranged in series to allow frequency responses of the stages (202) to be aggregated together. Each stage (202) may be programmable to insert a zero, thus causing the frequency response of the stage (202) to be increased in magnitude by 20 dB/decade. The frequency location of zero may also be programmable to allow each stage (202) to contribute to a certain amount of a gain for a specific frequency. Each stage (202) may also be programmable to determine the location of a pole for the reduction of high frequency noise and cross-talk cancellation.

    Abstract: PROBLEM TO BE SOLVED: To provide a data conversion process which can convert a serial data format to a parallel data format successfully and efficiently, and also to provide a data conversion process in the opposite direction. SOLUTION: The receiver circuitry for receiving high-speed serial data signals having serial bit rates in the range of about 10 Gbps includes a two-stage, continuous-time, linear equalizer having only two serially connected stages. Each of the stages has variable parameters of a DC gain, and a pole and/or zero whose location is variable with respect to frequency. The parameters of the DC gain at each stage and the locations of the pole and/or zero are variable by programs. COPYRIGHT: (C)2009,JPO&INPIT
