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.
