摘要： One embodiment sets forth a technique for time-multiplexed communication for transmitting command and address information between a controller and a multi-port memory device over a single connection. Command and address information for each port of the multi-port memory device is time-multiplexed within the controller to produce a single stream of commands and addresses for different memory requests. The single stream of commands and addresses is transmitted by the controller to the multi-port memory device where the single stream is demultiplexed to generate separate streams of commands and addresses for each port of the multi-port memory device.

摘要： A system and method for calibration of serial links using serial-to-parallel loopback. Embodiments of the present invention are operable for calibrating serial links using parallel links thereby reducing the number of links that need calibration. The method includes sending serialized data over a serial interface and receiving parallel data via a parallel interface. The serialized data is looped back via the parallel interface. The method further includes comparing the parallel data and the serialized data for a match thereof and calibrating the serial interface by adjusting the sending of the serialized data until the comparing detects the match. The adjusting of the sending is operable to calibrate the sending of the serialized data over the serial interface.

摘要： A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period.

摘要： A detection framework that matches anatomical structures using appearance and shape is disclosed. A training set of images are used in which object shapes or structures are annotated in the images. A second training set of images represents negative examples for such shapes and structures, i.e., images containing no such objects or structures. A classification algorithm trained on the training sets is used to detect a structure at its location. The structure is matched to a counterpart in the training set that can provide details about the structure's shape and appearance.

摘要： Techniques for performing frequency control in an OFDM system are described. In one aspect, frequency acquisition is performed based on a received pilot, and frequency tracking is performed based on received OFDM symbols. For frequency acquisition, an initial frequency error estimate may be derived based on the received pilot, and an automatic frequency control (AFC) loop may be initialized with the initial frequency error estimate. For frequency tracking, a frequency error estimate may be derived for each received OFDM symbol, and the AFC loop may be updated with the frequency error estimate. Frequency error in input samples is corrected by the AFC loop with the initial frequency error estimate as well as the frequency error estimate for each received OFDM symbol. In another aspect, a variable number of samples of a received OFDM symbol are selected, e.g., based on the received OFDM symbol timing, for use for frequency error estimation.
