Input/output integrated circuit hub incorporating a RAMDAC |
摘要 |
A computer system includes a first integrated circuit that has a central processing unit (CPU) and a graphics controller. An I/O hub, which is coupled to a plurality of input/output buses, includes a RAMDAC. An interconnect bus couples the first integrated circuit and the I/O hub and carries both graphics data to or from a frame buffer and also carries asynchronous system data between the processor and the input/output integrated circuit. The frame buffer may be located in the I/O hub to reduce graphics traffic over the interconnect bus.
