Abstract
A control chip supporting a plurality of buses and control chip set thereof is provided. A control chip supporting a plurality of buses chooses a type of bus for complying with another control chip based on the bus type thereby, wherein a device and a driving circuit are included. The device generates required controlling timings based on selection pins. The driving circuit enables required transmitting direction of pins based on selection pins per se.
Claims18
A control chip for supporting a plurality of buses, comprising:
- a device, for generating control timing of an operating bus based on a choice of at least one of a plurality of selection pins;
- and
- a driving circuit, coupled to said device, for enabling a plurality of bus pins of the control chip to comply with a specification of the operating bus based on the choice of the selection pin.
A control chip set, comprising:
- a first control chip having a first bus;
- and
- a second control chip for supporting a plurality of buses including the first bus and for generating a control timing complying with the first bus based on a choice of at least one of a plurality of selection pin.
A south bridge chip supporting a plurality of buses, comprising:
- a device for generating a control timing of an operating bus based on a choice of at least one of a plurality of selection pin;
- and
- a driving circuit electrically coupled to said device for enabling a plurality of bus pins of said south bridge chip to comply with a specification of the operating bus based on the choice of said selection pin.
A control chip set, comprising:
- a north bridge chip having a first bus;
- and
- a south bridge chip for supporting a plurality of buses including said first bus and for generating a control timing complying with said first bus based on a choice of at least one of a plurality of selection pin.
