摘要： Described herein are systems and methods for secure multithread execution. For example, some methods include fetching an instruction of a first thread from a memory into a processor pipeline that is configured to execute instructions from two or more threads in parallel using execution units of the processor pipeline; detecting that the instruction has been designated as a sensitive instruction; responsive to detection of the sensitive instruction, disabling execution of instructions of threads other than the first thread in the processor pipeline during execution of the sensitive instruction by an execution unit of the processor pipeline; executing the sensitive instruction using an execution unit of the processor pipeline; and, responsive to completion of execution of the sensitive instruction, enabling execution of instructions of threads other than the first thread in the processor pipeline.

摘要： A master integrated circuit (IC) chip includes transmit circuitry and receiver circuitry. The transmit circuitry includes a timing signal generation circuit to generate a first timing signal, and a driver to transmit first data in response to the first timing signal. A timing signal path routes the first timing signal in a source synchronous manner with the first data. The receiver circuitry includes a receiver to receive second data from a slave IC chip, and sampling circuitry to sample the second data in response to a second timing signal that is derived from the first timing signal.

摘要： Methods and apparatus for job scheduling in a programmable mixed-radix DFT/IDFT processor. In an exemplary embodiment, a method includes receiving a plurality of discrete Fourier transform (DFT) jobs. Each job identifies a computation of a DFT of a particular point size. The method also includes bundling selected jobs having a selected point size into a mega-job, and identifying a radix factorization for the selected point size. The radix factorization includes one or more stages and each stage identifies a radix computation to be performed. The method also includes computing, for each stage, the identified radix computations for the selected jobs in the mega-job. The radix computations for each stage are performed for the selected jobs before performing radix computations for a subsequent stage. The method also includes outputting DFT results for the selected jobs in the mega-job.

摘要： A packet processing system having each of a plurality of hierarchical clients and a packet memory arbiter serially communicatively coupled together via a plurality of primary interfaces thereby forming a unidirectional client chain. This chain is then able to be utilized by all of the hierarchical clients to write the packet data to or read the packet data from the packet memory.

摘要： A communication device selects a frequency bandwidth via which a physical layer (PHY) protocol data unit (PPDU) will be transmitted in a vehicular communication network, and generates, the PPDU i) according to a downclocking ratio of 1/2, and ii) based on an orthogonal frequency division multiplexing (OFDM) numerology defined by an IEEE 802.11ac Standard. In response to the selected frequency bandwidth being 10 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 20 MHz PPDUs. In response to the selected frequency bandwidth being 20 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 40 MHz PPDUs.

摘要： Systems and methods are provided for introducing time diversity in a transmitter. The systems and methods may include receiving, at the transmitter, a request from a receiver to retransmit data. The systems and methods may further include receiving an input of data corresponding to the data requested for retransmission at a first transmitter block. The systems and methods may further include operating on the signals using the first transmitter block in at least one of a first mode and a second mode, such that an output of signals from the first transmitter block is dependent on a time-varying function and corresponds to the data requested by the receiver for retransmission.

摘要： Forming a metal gate transistor includes forming a semiconductor channel in a substrate, and depositing a source electrode and a drain electrode on the semiconductor channel. The source and drain electrodes are spaced apart. Dielectric spacers are provided above the source and drain electrodes to define a gate void spanning the source and drain electrodes. A dielectric layer is deposited on a bottom wall and sidewalls of the gate void. A work-function metal layer is deposited on the dielectric layer. The work-function metal layer is etched away from the sidewalls leaving the work-function metal layer on the bottom wall to control work function between the semiconductor channel and a conductive metal gate material to be deposited. The gate void above the work-function metal layer on the bottom wall, and between the dielectric layers on the sidewalls, is filled with the conductive metal gate material.

摘要： A preamble of physical layer (PHY) data unit includes a first legacy portion and a first non-legacy portion that follows the first legacy portion. The first non-legacy portion includes i) a first orthogonal frequency division multiplexing (OFDM) symbol that immediately follows the first legacy portion and that is modulated using binary phase shift keying (BPSK), and ii) a second OFDM symbol that immediately follows the first OFDM symbol and that is modulated using BPSK modulation rotated by 90 degrees (Q-BPSK). The modulation of the first and second OFDM symbols indicates to a receiver device that conforms to a first communication protocol that the data unit conforms to the first communication protocol. The first OFDM symbol being modulated using BPSK modulation causes a receiver device that conforms to a second communication protocol to determine that the PHY data unit conforms to a third communication protocol.

摘要： A communication device includes a convolutional interleaver and an encoder. The convolutional interleaver is configured to receive blocks of data defining symbol blocks that are encoded using a block code to correct an error in a block of data and to interleave the symbol blocks into a stream of interleaved symbol blocks. The encoder is configured to encode a set of symbol blocks among the interleaved symbol blocks with an error-correcting code to correct single bit errors in the set of symbol blocks. The error-correcting code is configured to generate an error-correcting block and to add the error-correcting block to the set of interleaved symbol blocks.

摘要： Decompressing a compressed image to obtain a decompressed image includes receiving, in a compressed stream, compressed pixel values of the compressed image; decompressing, from the compressed stream, a first compressed pixel value of the compressed pixel values using a lossy floating-point decompression scheme to obtain a floating-point pixel value; rounding the floating-point pixel value to a nearest integer to obtain a pixel value of the decompressed image; and displaying or storing the decompressed image.
