Computer system and main board equipped with hybrid hypertransport interfaces

Abstract

A computer system comprises a main board equipped with a HT device. The HT interface comprises a first connector and a riser card. The first connector is compatible with HT Device-Under-Test (HT-DUT) specifications and electrically connected onto the main board. The riser card, inserted onto the main board, includes a second connector compatible with HT-DUT specifications and a third connector compatible with HT expansion (HTX) specifications. The first connector and the second connector are electrically connected for data transmission. Therefore, the main board equipped with both the HT-DUT connector and the HTX connector achieves smaller on-board space and fewer on-board connection interfaces.
