ABSTRACT:
A single chip replacement upgradeable/downgradeable data processing system capable of operating with different types of central processing unit (CPU) chips. The system has a first socket for registration of a first CPU chip and a second socket for registration of a second CPU chip. Circuitry is provided for preventing possible signal contention between the first and second CPU chips and for synchronizing clocks for operating a CPU with the system clock. Circuitry is also provided for interfacing with a coprocessor associated with the different types of CPU chips as well as for adjusting the signals to and from the CPU chips to the signal width of the system.
