A computing device and a method of flashing VBIOS instructions are provided. The computing device comprises non-volatile system memory and a graphics processor. The graphics processor is in communication with the non-volatile system memory and comprises additional non-volatile memory. The graphics processor is configured to: prior to flashing video basic input/output system (VBIOS) instructions, write a copy of a portion of the VBIOS instructions from the additional non-volatile memory to the non-volatile system memory; flash the VBIOS instructions; on a condition that the flashing of the VBIOS instructions is stopped before completion, write the copy of the portion of the VBIOS instructions from the non-volatile system memory to the additional non-volatile memory; and re-flash the VBIOS instructions using the copy of the portion of the VBIOS instructions.

An antenna selection method includes selecting Mantenna sets from Cantenna combinations, where Lis a quantity of reserved antennas, a sum of Land Lis equal to L, determining an antenna set with a maximum channel capacity, in Mantenna sets, as a target antenna set to perform a preset-duration data transmission, where the Mantenna sets are antenna sets formed by the Mantenna sets and the Lreserved antennas. The Lreserved antennas include a maximum SNR in a target antenna set used in previous preset-duration data transmission. Each of the Mantenna sets includes the Lreserved antennas.

Antenna selection method and device

A terminal includes a conductive substrate and a printed circuit board that are disposed opposite to each other, a first slot is disposed in a direction from a first side edge of the conductive substrate to a center of the conductive substrate, and a projection of the printed circuit board on the conductive substrate is located inside the conductive substrate, and a first feeder is disposed inside the first slot, a first connection end of the first feeder is coupled to a lap joint of the first side edge, a second connection end of the first feeder is coupled to a first feeding source on the printed circuit board, and projections of the lap joint of the first side edge and the first feeding source on the conductive substrate are located on two sides of the first slot.

Terminal

This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.

Slot antenna and terminal
