Abstract
Embodiments of the present invention provide a computer system with a high speed, high bandwidth expandability bus for integrated and non-integrated CPU products. The computer system includes a processor, a chipset coupled to the processor, a graphics processor coupled to the chipset for controlling a video display and a main memory coupled to the chipset. The computer system further includes an expandability bus, which is coupled at one end to the chipset and at the other end to a replaceable electronic component. The expandability bus can be changeably configured to enable or disable bus mastering at both ends, as required, to operate with whichever replaceable electronic component is installed.
Claims27
A computer system with a high speed, high bandwidth expandability bus comprising:
- a processor;
- a chipset coupled to said processor;
- an expandability bus coupled at a first end to said chipset;
- and
- an electronic component coupled to a second end of said expandability bus, said expandability bus being configurable to enable bus mastering at said first and second ends and said expandability bus being configured to operate with said electronic component;
- said electronic component being replaceable and said expandability bus being changeably configurable to operate with a replacement electronic component.
A computer system with a high speed, high bandwidth expandability bus comprising:
- a processor means;
- a chipset means coupled to said processor means;
- an expandability bus means coupled at a first end to said chipset means;
- and
- an electronic component means coupled to a second end of said expandability bus means, said expandability bus means being configurable to enable bus mastering at said first and second ends and said expandability bus means being configured to operate with said electronic component means;
- said electronic component means being replaceable and said expandability bus means being changeably configurable to operate with a replacement electronic component means.
An integrated processor computer system with a high speed, high bandwidth expandability bus comprising:
- an integrated processor;
- a chipset coupled to said processor;
- a first expandability bus coupled at a first end to said integrated processor;
- an electronic component coupled at a second end to said expandability bus, said expandability bus being configurable to enable bus mastering at said first and second ends and said expandability bus being configured to operate with said electronic component, said electronic component being replaceable and said expandability bus being changeably configurable to operate with a replacement electronic component;
- and
- a main memory coupled to said integrated processor using a second expandability bus.
A multi-processor computing system with a high-speed, high-bandwidth expandability bus comprising:
- a first processor;
- a second processor coupled to said first processor;
- a chipset coupled to at least one of said first and second processors;
- a graphics processor coupled to one of said first processor, said second processor and said chipset for controlling a video display;
- a main memory coupled to one of said first processor, said second processor and said chipset;
- and
- an expandability bus coupled at a first end to one of said first processor, said second processor and said chipset;
- and
- an electronic component coupled to a second end of said expandability bus, said expandability bus being configurable to enable bus mastering at said first and second ends and said expandability bus being configured to operate with said electronic component;
- said electronic component being replaceable and said expandability bus being changeably configurable to operate with a replacement electronic component.
