ABSTRACT:
A programmable logic device in accordance with an embodiment of the invention includes configurable logic blocks, embedded random access memory (RAM) blocks, and input/output blocks adapted to transfer information into or out of the programmable logic device. An interconnect architecture is adapted to route information among the configurable logic blocks, embedded RAM blocks, and input/output blocks within the programmable logic device. An interface block is provided that couples an embedded RAM block and an input/output block but not a logic block to the interconnect architecture.
