The disclosed embodiments provide a system that uses broadcast-based TLB-sharing techniques to reduce address-translation latency in a shared-memory multiprocessor system with two or more nodes that are connected by an electrical interconnect. During operation, a first node receives a memory operation that includes a virtual address. Upon determining that one or more TLB levels of the first node will miss for the virtual address, the first node uses the electrical interconnect to broadcast a TLB request to one or more additional nodes of the shared-memory multiprocessor in parallel with scheduling a speculative page-table walk for the virtual address. If the first node receives a TLB entry from another node of the shared-memory multiprocessor via the electrical interconnect in response to the TLB request, the first node cancels the speculative page-table walk. Otherwise, if no response is received, the first node instead waits for the completion of the page-table walk.

The invention relates to a method for acquiring area troposphere zenith delay. The method comprises the following steps of: 1) dividing a tested area into grids and setting the size and an attenuation factor of each grid; 2) acquiring the zenith total delay value of each reference station in the tested area in real time, acquiring the values of dry and wet delay according to a GPT function, computing the zenith delay modified value of each reference station; 3) computing the zenith delay modified value of each grid by using an inverse distance weighting interpolation algorithm equipped with the attenuation factor according to zenith delay modified value of all reference stations; 4) acquiring the delay modified value of a user station by using inverse distance weighting interpolation, and acquiring a user station troposphere zenith delay value; 5) and verifying the precision of the user station troposphere zenith delay value, returning to the step 1) if the precision does not satisfy a requirement or recording the user station troposphere zenith delay value if the precision satisfies the requirement. Compared with a method in the prior art, the method has advantages of full consideration, easy operation, convenient broadcast, and high precision.

The present invention relates to a method and a device for filtering a novel custom Ethernet out-band data packet. The key of the method and the device is that a filter module is additionally arranged between the out-band management interface of the Ethernet switcher and the CPU to extract the keyword of the data packet, to filter the content of the relative data packet, and to operate the discarding or the flow control operation. The method and the device can provide one to seven layers of filtering to the Ethernet out- band data packet, to pre filters the layer 2 or layer 3 or layer 4 data packets used to be processed by the CPU, and the present invention can pre process the special protocol data packets such as an Ethernet broadcast packet, a multicast packet, other Ethernet management protocols, the IP and a high-level IP protocol data packet, an ICMP and an ARP, etc., therefore, the processing efficiency of the CPU is improved, and the overload operation caused by the protocol data packets flooding is avoided, thereby the reliability of the complete Ethernet switcher system is improved.

The invention relates to an assistive listening system comprising an audio transmitting device adapted for transmitting an audio signal and/or a control signal to a multitude of receiving listening devices and at least one receiving listening device adapted for receiving said audio signal and said control signal from said audio transmitting device. The invention further relates to a method of operating an assistive listening system and to its use. The object of the present invention is to provide an assistive listening system suitable for servicing a multitude of body worn listening devices in a wireless environment. The problem is solved in that the system is adapted to establish a digital link according to the DECT-standard from the audio transmitting device to the at least one receiving listening device, wherein the system is adapted to provide that said link is uni-directional. The system has the advantage of providing a reliable channel selection in a wireless assistive listening system comprising low power, body worn listening devices. The invention may e.g. be used for public address systems, e.g. educational listening systems, comprising listening devices adapted for being worn by a user.

The present invention discloses a denoising method, device and system. The method is applied to an earphone, the earphone is equipped with a microphone and an earphone loudspeaker, and the microphone is used for acquiring the sound information of the users. The method comprises the steps of using the microphone to acquire the current environmental noise information when the situation that there is currently existed the to-be-played audio information or the audio information is being played currently, is determined; according to the environmental noise information obtaining the anti-noise information; superposing the anti-noise information and the audio information to obtain the superposed audio information; playing the superposed audio information via the earphone loudspeaker. According to the technical scheme, when the to-be-played audio information is detected or the audio information is being played, the microphone does not acquire the sound of the users at the moment, so that the microphone can acquire the environmental noise, then the anti-noise information is obtained according to the environmental noise, and further the noise is reduced according to the anti-noise information, and accordingly, a scheme of arranging the microphone on the earphone to denoise is realized, the structure of the earphone is simplified, and the manufacturing cost of the earphone is reduced.

The invention provides a satellite locating pseudorange difference method.
