摘要： Embodiments of the present invention provide a system that executes a branch instruction. When executing the branch instruction, the system obtains a stored prediction of a resolution of the branch instruction and fetches subsequent instructions for execution based on the predicted resolution of the branch instruction. If an actual resolution of the branch instruction is different from the predicted resolution (i.e., if the branch is mispredicted), the system updates the stored prediction of the resolution of the branch instruction to the actual resolution of the branch instruction. The system then re-executes the branch instruction. When re-executing the branch instruction, the system obtains the stored prediction of the resolution of the branch instruction and fetches subsequent instructions for execution based on the predicted resolution of the branch instruction.

摘要： A system which regulates communication with a server is described. During operation, the system determines a retransmission rate of data packets during a first set of conversations between a group of users and the server via a peering link. Next, the system compares the retransmission rate and an historical retransmission rate of data packets during a second set of conversations between a second group of users and the server via the peering link. The system then adjusts a target acceptance rate of the server to requests to initiate conversations with additional users via the peering link based on the comparison of the retransmission rate and the historical retransmission rate. Additionally, the system accepts or rejects a request to initiate a conversation between another user and the server via the peering link based on an actual acceptance rate of the server to requests to initiate the conversations and the target acceptance rate.

摘要： Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The reconstructed request is then provided to the server. Accelerations may occur in any direction of communication. Persistent segment stores can be pre-populated with segment data from other transaction accelerators and anticipated transactions. The persistent segment store can store segments that are data segmented based on content of the data and can be independent of transaction protocol, application, and device.

摘要： A system that activates a muscle to produce a functional movement in a subject through electrical stimulation is described. During operation, the system first obtains a non-isometric model which defines a functional movement associated with the muscle in response to electrical stimulation of the muscle. Next, the system uses the non-isometric model to compute an electrical stimulation which produces a desired functional movement in the subject. The system then applies the computed electrical stimulation to the muscle to produce the desired functional movement in the subject.

摘要： One embodiment of the present invention provides a system that facilitates adjusting the wavelengths of lasers via temperature control. This system includes a chip with an active face upon which active circuitry and signal pads reside. A thermal-control mechanism provides localized thermal control of two lasers mounted upon the active face of the chip. By individually controlling the temperature of the lasers, the thermal-control mechanism controls the wavelengths emitted by each respective laser. By creating a temperature gradient that causes a temperature difference between two or more lasers, the system can cause the lasers to emit different wavelengths.

摘要： One embodiment of the present invention provides a system that parallelizes the TCP-related actions of a network connection between two computer systems during a data transfer between the two computer systems. During operation, the first computer system partitions the data into two or more data segments, and assigns the data segments to multiple processing elements. These multiple processing elements subsequently prepare and send their assigned data segments to the second computer system in parallel using TCP.

摘要： One embodiment of the present invention provides a system and a method for performing a page-table lookup in a manner that supports adaptive page sizes. During operation, the system receives a virtual address. Next, the system looks up this virtual address in a page table. Since each entry in the page table maintains a page size, the lookup process involves using the page size to determine the number of bits that must be compared to find a matching page table entry. A page table entry matches the virtual address if the determined number of bits in the virtual address match the virtual address in the page table entry. If a matching page table entry is found, the system returns the physical page address from the matching page table entry.

摘要： The disclosed embodiments relate to the design of a system that uses an accelerometer in a mobile device to detect hotwords, which activate a voice interface to recognize subsequent voice input. During operation, the system gathers samples comprising readings from the accelerometer in the mobile device. Next, the system calculates features from the gathered samples. The system then classifies the calculated features using a classifier, which has been trained to detect hotwords based on calculated features. Finally, if the classifier detects one or more hotwords, the system causes the mobile device to launch a voice-control system that recognizes subsequent voice input received from an audio microphone.

摘要： An integrated circuit includes an optical source (such as a laser) with a lens, which is disposed on an isolator. This isolator is disposed on a semiconductor layer in a silicon-on-insulator (SOI) platform that includes an optical coupler and an optical waveguide. During operation, the optical source generates an optical signal that propagates toward the isolator so that the lens focuses the optical signal. Furthermore, the isolator reduces or eliminates back reflection of the optical signal toward the optical source, and the optical coupler couples the optical signal into the optical waveguide.
