  • Integration of externally developed logic in a memory mapped system
    Patent number: 6460164
    Abstract: An integrated circuit comprises an application-non-specific library cell, externally developed logic circuitry integrated with the library cell, and an up-integration module (UIM) connected to the library cell and to the logic circuitry and providing a two-way interface between the library cell and the logic circuitry and between the library cell and an external device. The logic developed for a prototype system comprising such a library cell in association with external logic circuitry can be integrated into the circuit without requiring any change in its function or in the program code developed for the prototype system.
