1. A unified configurable memory architecture for emulation comprising:

  • a physical memory divided into a plurality of segments; and

    a programmable logic chip coupled to said physical memory and implementing a controller function, said controller function comprising;

    a set associative memory coupled to said physical memory, where said set associative memory maps at least one of a plurality of sets into a least one of said plurality of segments;

    an address input multiplexer for processing addresses associated with said plurality of sets, and switching one of said addresses onto main address lines;

    a data input multiplexer for processing a plurality of data lines associated with said plurality of sets, and switching one of said plurality of data lines onto main data lines; and

    a sequencer, for providing time slots for said plurality of sets, coupled to said set associative memory.
