摘要： In an image/video encoding and decoding system employing an artifact evaluator a method and/or apparatus to process video blocks comprising a decoder operable to synthesize an un-filtered reconstructed video block or frame and an artifact filter operable to receive the un-filtered reconstructed video block or frame, which generates a filtered reconstructed video block or frame. A memory buffer operable to store either the filtered reconstructed video block or frame or the un-filtered reconstructed video block or frame, and an artifact evaluator operable to update the memory buffer after evaluating and determining which of the filtered video block or frame, or the un-filtered video block or frame yields better image/video quality.

摘要： A method includes executing, at a processor, a dedicated arithmetic encoding instruction. The dedicated arithmetic encoding instruction accepts a plurality of inputs including a first range, a first offset, and a first state and produces one or more outputs based on the plurality of inputs. The method also includes storing a second state, realigning the first range to produce a second range, and realigning the first offset to produce a second offset based on the one or more outputs of the dedicated arithmetic encoding instruction.

摘要： Systems, methods, and devices for reducing shadow effects in touch systems are contained herein. In one aspect, a method of reducing shadow effects in a touch system is disclosed. The method includes receiving a touch input on a touch interface, determining a difference between a weighted mean of the touch input and an arithmetic mean of the touch input and adjusting an estimated touch position of the touch input based on the difference.

摘要： Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes.

摘要： In the various aspects, virtualization techniques may be used to improve performance and reduce the amount of power consumed by translating virtual memory addresses into physical addresses on a computing system having hybrid memory. In a first stage of memory translation, an operating system translates virtual addresses to intermediate physical addresses. In a second stage of memory translation, a chip or virtualization software translates the intermediate physical address to physical addresses based on the characteristics of the physical memory and the characteristics of the processes associated with the physical memory.

摘要： As part of a video encoding or decoding operation on video data, a video coder performs a coding operation for a current video unit of the video data. As part of performing the coding operation for the current video unit, the video coder determines the availabilities of one or more video units that neighbor the current video unit. In order to determine the availability of a video unit that neighbors the current video unit, the video coder identifies, based on availabilities of video units that neighbor a parent video unit of the current video unit, an entry in a lookup table. The identified entry indicates the availability of the video unit that neighbors the current video unit. The video coder then performs a coding operation on the current video unit based on whether the video unit that neighbors the current video unit is available.

摘要： A dynamically scaled file encoding method and apparatus are disclosed. A file encoding system using JPEG encoding can be configured to produce relatively constant compressed file sizes irrespective of the initial file size and file contents. The system retrieves an initial file or image that is to be compressed and determines a target bit rate corresponding to the compressed file. The target bit rate is used to determine an initial scaling factor. The initial file is encoded using a JPEG encoder having coefficients scaled by the initial scaling factor. The resultant bit rate can be adjusted in a second loop if greater than the desired bit rate. To adjust the bit rate, a recomputed scaling factor is determined from the resultant bit rate. The initial file is then encoded with coefficients scaled by the recomputed scaling factor to achieve a bit rate that is within the target bit rate.

摘要： A voice recognition (VR) system is disclosed that utilizes a combination of speaker independent (SI) (230 and 232) and speaker dependent (SD) (234) acoustic models. At least one SI acoustic model (230 and 232) is used in combination with at least one SD acoustic model (234) to provide a level of speech recognition performance that at least equals that of a purely SI acoustic model. The disclosed hybrid SI/SD VR system continually uses unsupervised training to update the acoustic templates in the one ore more SD acoustic models (234). The hybrid VR system then uses the updated SD acoustic models (234) in combination with the at least one SI acoustic model (230 and 232) to provide improved VR performance during VR testing.
