ABSTRACT:
A method and apparatus for a memory efficient hardware emulator. The emulator comprises a plurality of processor dusters having data within the duster is stored in at least one data array, where the at least one data array comprises a plurality of sub-arrays. The sub-arrays that are not of uniform size (e.g., the size of each sub-array is determined by the probability that a particular sub-array will be accessed by the processor during a future emulation step). For example, at least one first sub-array is equal in depth to instruction memory within a processor (i.e., equal to the number of instructions in an emulation cycle), and the remaining sub-arrays are a fractional depth of the first sub-array.
