Abstract: A storage system, a file storage and reading method, and a terminal device are provided. A storage system including a UFS is used as an example. The storage system configures different medium forms of the UFS, for example, configures persistent storage space of the UFS including SLC and TLC medium forms, to implement hybrid medium multi-disk storage.

Abstract: This application relates to the field of mobile communications, and in particular, to a technical solution of sharing data with a nearby device by using a wireless communications technology. In a method for printing a photo, a mobile phone first selects a to-be-printed photo, then discovers a nearby device by using the foregoing related wireless communications technology, and displays the discovered device such as a printer or a projector on the mobile phone; and then a user performs a tap operation on the discovered printer, so that one-tap printing can be implemented. In this way, printing efficiency of an electronic device is improved, and user experience is also improved.

Abstract: A floating-point operation control method, applied to a chip comprising a multiply accumulator, includes receiving a first selection signal, and controlling an operation circuit in the multiply accumulator corresponding to a floating-point operation mode indicated by the first selection signal. The floating-point operation mode supports a multiply accumulate operation of a floating-point number of a first bit width k1. The method further includes dividing fractional parts of first and second operands into m first and second suboperands of a second bit width k2. The second bit width k2=k1/m. The method further includes performing a multiplication operation based on the m first and second suboperands to obtain a fractional product, and determining a floating-point number sum based on the fractional product and a third operand.
