Abstract: An open-ear earphone includes a housing, a chamber is provided inside the housing, a speaker is provided inside the chamber and divides the chamber into a front chamber and a rear chamber. The housing is provided with a first sound hole and a second sound hole. The front chamber is communicated to the outside through the first sound hole, and the rear chamber is communicated to the outside through the second sound hole. The rear chamber includes a first volume down chamber and a second volume down chamber communicated to the first volume down chamber, and the first volume down chamber is located between the speaker and the second volume down chamber. The sound wave in backward motion generated by the speaker is transmitted to the outside from the second sound hole after being reduced by the first volume down chamber and the second volume down chamber.

Abstract: An open-ear Bluetooth® earphone includes an earphone body and a support frame. The support frame is configured to be plugged into a cavum concha of a wearer. The earphone body is provided with an audio source, and the support frame is installed on the earphone body and corresponds to the audio source. When in use, the support frame is configured to be firmly plugged into the cavum concha of the wearer to allow the earphone body to be worn on the ear of the wearer. The audio source corresponds to the ear canal of the wearer through the support frame, so that the sound emitted from the audio source is transmitted into the ear canal through the support frame. The audio source is directly opposite of the ear canal through the support frame to shorten the distance between the audio source and the ear canal.

Abstract: A computing system with a first instruction of an instruction set architecture (ISA) for write-back and invalidation in a hierarchical cache structure based on one single designated key identification code, and a second instruction of ISA for write-back and invalidation in the hierarchical cache structure based on a plurality of designated key identification codes is shown. A decoder transforms the first or second instruction into at least one microinstruction. Based on the at least one microinstruction, one write-back and invalidation request is provided corresponding to each designated key identification code, to be passed to the hierarchical cache structure through a memory ordering buffer. For each write-back and invalidation request, the cache line write-back and invalidation regarding a designated key identification code is performed on a last-level cache first, and then is performed on the in-core cache modules.

The ground truth video frames correspond to the training video frames.

Abstract: A processor with an elliptic curve cryptographic algorithm and a data processing method thereof are shown. Three elliptic curve cryptographic instructions are proposed in the instruction set architecture for key exchange between an initiator and a responder. The initiator device executes the first elliptic curve cryptographic instruction to generate a key pair (rA, RA). In addition to considering the first temporary public key RA, the responder device further takes the second temporary public key RB into consideration when executing the second elliptic curve cryptographic instruction to generate the responder-generated shared key KB. Based on the temporary private key rA, and the temporary public keys RA and RB, the initiator device executes the third elliptic curve cryptographic instruction to generate the initiator-generated shared key KA.
