Abstract: A peripheral device to generate read and write cycles on a PCI bus comprises a PCI bus interface. A control unit has a data pattern generator to source a data pattern to a target via the interface during a write operation and to verify an incoming data pattern from the interface during a read operation.

Abstract: A golf mat of grass-like material includes top and bottom pads each of which includes belting material which substantially strengthens them and protects the base mat form damage from golf clubs striking it. The golf tee extends only through the top pad and not through the base mat and the belting material of the top pad presents any enlargement of the hole through the top pad which includes felt carpet which also gives a grass-like appearance. The top pad is loosely secured to the base pad and may be raised at its center for replacement of the tee and the top pad absorbs energy from the golf club due to its ability to move relative to the base mat when it is struck. The pad may be replaced through operation of the bolts at its opposite ends. The turf layer includes filaments of yarn such as tufts partially exposed on the bottom side adjacent fabric-like material exposed on the top side of the layer of belting material.
