  • Patent number: 8594991
    Abstract: A memory mapping system for compactly mapping dissimilar memory systems and methods for manufacturing and using same. The mapping system maps a source memory system into a destination memory system by partitioning the source memory system and disposing memory contents within the partitioned source memory system into the destination memory system. In one embodiment, the mapping system factorizes a source data width of the source memory system in terms of a destination data width of the destination memory system to form at least one data sub-width. A source memory sub-region is defined for each data sub-width. The memory contents associated with each source memory sub-region are disposed within the destination memory system in a side-by-side manner across selected destination memory registers of the destination memory system. The mapping system thereby can compactly map the memory contents into the destination memory system without a loss of valuable memory space.

  • Patent number: 7937258
    Abstract: A memory mapping system for providing compact mapping between dissimilar memory systems and methods for manufacturing and using same. The memory mapping system can compactly map contents from one or more first memory systems into a second memory system without a loss of memory space in the second memory system. Advantageously, the memory mapping system can be applied to hardware emulator memory systems to more efficiently map design memory systems into an emulation memory system during compilation.
