Abstract
An apparatus and method are provided for operating a PCI-X bus. A device may be provided to determine a number of PCI-X cards coupled to the bus. A mechanism may be provided to control a frequency of the PCI-X bus based on the determined number of PCI-X cards coupled to the bus.
Claims10
A system comprising:
- a processor;
- a memory to store instructions;
- a front side bus coupled between the processor and the memory;
- a peripheral bus;
- a mechanism coupled between the front side bus and the peripheral bus;
- a a plurality of slots coupled to the peripheral bus;
- and
- a logic circuit coupled to a first slot of the plurality of slots, the logic circuit to receive a first signal to indicate whether a first card is present in the first slot;
- wherein the mechanism is further coupled to the logic circuit to control a frequency of the peripheral bus based on a number of cards present in the plurality of slots.
6 more elements
A method comprising:
- coupling a logic circuit between a plurality of slots associated with a bus and a frequency control circuit, the logic circuit to receive a first signal to indicate whether a first card is present in a first slot of the plurality of slots;
- and
- causing the frequency control circuit to control a frequency of the bus based on a number of cards present in the plurality of slots.
