    Abstract: A high-performance programmable logic architecture has embedded memory (608). arranged at the 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) are organized in rows along the top and bottom edges of the integrated circuit. The logic elements (805) can be directly programmable routed and connected to driver blocks (809) of the logic block in adjacent rows and columns. This permits fast interconnection of signals without using the global programmable interconnect resources (815, 825). Using similar direct programmable interconnections (828, 830, 835), 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 integrated circuit device has logic modules with some inputs that are optimized for speed (to enhance the speed-performance of the logic modules). For example, some of the inputs may be programmably swappable within a logic module so that a speed-critical input signal can be more easily routed to a faster part of the logic module circuitry. Alternatively or in addition, drivers may be added to the logic module circuitry to improve the speed performance of some of the inputs to the logic module. The logic module may be provided with enhanced “lonely register” circuitry which allows the lonely register output signal to be fed back for use as an input to the combinatorial logic of the logic module. The registers in multiple logic modules may be directly chained to one another in a series.

    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: Driver circuitry for programmable logic devices may include a module comprising a driver and associated hardware-programmable input and/or output routing connection. Instances of the generalized driver module may be included anywhere on the programmable logic device that driver circuitry having characteristics within the capabilities of the generalized module is needed. The circuitry of each instance of the module is hardware-customized to match the driver characteristics required for that instance. Driver circuits may be distributed throughout the interconnection conductor resources of the programmable logic device in such a way as to optimize re-buffering of signals propagating through those resources.
