A microprocessor assembly is located on a daughterboard, which is configured to be physically and electrically coupled to a motherboard. One of the electrical terminals in an electrical connector between the daughterboard/motherboard is coupled to either a ground or a voltage supply V on the daughterboard, depending on the type of microprocessor used. The electrical connector passes either the ground or V signal to a semiconductor device on the motherboard to automatically identify the type of microprocessor on the daughterboard.

Method and apparatus for automatically identifying a central processing unit

A method and apparatus for providing one of two clock signals to a processor based on a reference signal. An electronic component includes a processor, a first clock source configured to provide a first clock signal, an interface for receiving a second clock signal, and a reference signal line. The first clock signal is applied to the processor if a first reference signal is applied to the reference signal line, and the second clock signal is applied to the processor if a second reference signal is applied to the reference signal line.

Method and apparatus for providing a clock signal to a processor

A method and apparatus for converting a signal from a first voltage level to a second voltage level before providing the signal to a processor. A circuit board includes an interface for coupling the circuit board to a peripheral subsystem via a socket. The circuit board also includes a processor that receives signals of a first voltage level, a first signal line, and a second signal line. The first signal line is coupled to the interface and provides a reference signal to the peripheral subsystem that indicates the first voltage level. The second signal line is also coupled to the interface and provides a subsystem signal back from the peripheral subsystem after the signal has been converted to the first voltage level.

Method and apparatus for providing a processor module for a computer

A method and apparatus for upgrading a computer system from one processor generation to another processor generation. The processor and its corresponding primary bridge are included together on the same circuit board. The circuit board has an interface which can be inserted into a socket of a system. The interface socket includes the memory bus and peripheral component bus from the bridge.

Method and apparatus for upgrading a computer system

A method and apparatus for regulating a voltage supplied by a power supply to an integrated circuit. A signal is sent to the power supply. This signal signifies that a change in the current drawn by the integrated circuit from the power supply will occur. Next, the voltage supplied by the power supply to the integrated circuit is adjusted in response to this signal before the change in current occurs. The adjustment is in a direction that will compensate for the anticipated voltage transient that will result from the change in the current.

Method and apparatus for regulating the voltage supplied to an

A method and apparatus for adjusting the clock frequency and voltage supplied to an integrated circuit. First, a signal is sent to the clock, and in response, the clock lowers the clock frequency supplied to the integrated circuit. The clock sends a signal to the voltage regulator whereupon the voltage regulator reduces the voltage supplied to the integrated circuit.
