摘要： An inline scaling unit configured to retime an input video frame is disclosed. The scaling unit is configured to receive pixels within a line of a video frame to be displayed on a primary display that is within a first clock domain. The scaling unit down-scales the group of pixels and writes the down-scaled pixels to a buffer circuit in the first clock domain. The scaling unit includes a control circuit configured to generate horizontal and vertical control signals for the retimed video frame to be displayed on a secondary display that is within a second clock domain. The horizontal and vertical control signals are then used to enable reading from the buffer circuit in the second clock domain. The scaling unit outputs the down-scaled pixels and the generated control signals within the retimed video frame such that input video frame and the retimed video frame may be displayed concurrently.

摘要： Methods and apparatuses for providing virtual temperature sensor to control temperatures in a data processing system. In one aspect, a data processing system includes a virtual temperature sensor to provide system temperature for different system configurations, and a controller coupled to the sensor to control operations of the data processing system according to the virtual temperature. The virtual temperature sensor typically derives the temperature of a particular configuration of the data processing system using mathematical models or one or more operating parameters of the data processing system. In one example, the mathematical models include a characterization table which provides the measured temperature data from various system configurations. These measurements are performed with temperature sensors positioned in ideal locations for different configuration, and are preprocessed to provide the virtual temperature computation. The characterization table also includes thermal characteristics, such as thermal time constant and thermal resistance, of the critical components at multiple thermal control states.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating a device dependent cryptographic key in a rate-limited way. A system configured to practice the method first receives data associated with a user. The data associated with the user can be a password, a personal identification number (PIN), or a hash of the password. Then the system performs a first encryption operation on the user data based on a device-specific value to yield first intermediate data and performs a second encryption operation on the first intermediate data based on the device-specific value to yield second intermediate data. Then the system iteratively repeats the second encryption operation until a threshold is met, wherein each second encryption operation is performed on the second intermediate data from a previous second encryption operation. The iterations produce a final cryptographic key which the system can then output or use for a cryptographic operation.

摘要： A technique is provided for processing decoded video data to mask visual compression artifacts resulting from video compression. In accordance with this technique, a hardware block is provided for generating and adding random noise to the decoded video stream. In one embodiment, a random number is generated for each pixel of the decoded video data and compared against one or more threshold values to determine a threshold range. In such an embodiment, a noise addend value is selected based upon the threshold comparison and summed with the current pixel. While the present technique may not eliminate the compression artifacts, the addition of random noise renders the compression artifacts less noticeable to the human eye and, therefore, more aesthetically pleasing to a viewer.

摘要： A scaling unit is disclosed that is within a computing device having an internal display and an external interface. The scaling unit facilitates the concurrent presentation of images on the internal display and an external display connected to the external interface. In configurations in which the external interface does not have sufficient data width to concurrently display images on the external display at the same resolution as the internal display, the scaling unit may be used to reduce the number of pixels in a line, thus reducing bandwidth requirements at the external interface. The scaling unit may also scale further to maintain an aspect ratio of the image displayed on the internal display. Further vertical scaling may be performed outside the computing device (e.g., by a dongle coupled between the computing device and the external display), such that the scaling unit may be implemented with reduced memory requirements.

摘要： Accordingly, there is disclosed herein an augmented Fibre Channel (FC) frame format which may provide support for multiple fabric FC networks, and may improve the performance of modularly-constructed switches. In one embodiment, the augmented FC frame format is modulated on a carrier signal and the frame includes: a start-of-frame field; a supplementary header field that follows the start-of-frame field; a frame header field that follows the supplementary header field; a cyclic redundancy code (CRC) checksum field; and an end-of-frame field that follows the CRC checksum field. The supplementary header field may include a destination tag that identifies a target fabric to which the frame is directed. Alternatively, or in addition, the supplementary header field may include an egress port identifier that identifies a switch port through which the frame is to exit a switch. The supplementary header may also include flags to request special handling by the receiver.
