摘要： A multi channel encoder (100) comprises a multi channel linear predictive analyzer (105) for linear predictive coding of a multi channel signal. A prediction controller (101) comprises a prediction parameter generator (301) which generates linear prediction coding parameter matrices for the multi channel signal which are then mapped to reflection matrices. The reflection matrices may specifically be normalized backward or forward reflection matrices. The reflection matrices are encoded by a reflection parameter encoder (305) and combined with other encoded data in a multiplexer (109) to generate encoded data for the multi channel signal. The reflection parameter encoder (305) may specifically decompose the reflection matrices using an Eigenvalue decomposition or a singular value decomposition and the resulting data may be quantized for transmission. A decoder (200) receives the encoded data and obtains the prediction parameters by performing the inverse operation.

摘要： An apparatus and method is described herein for replacing faulty core components. General purpose hardware is provided to replace core pipeline components, such as execution units. In the embodiment of execution unit replacement, a proxy unit is provided, such that mapping logic is able to map instruction/operations, which correspond to faulty execution units, to the proxy unit. As a result, the proxy unit is able to receive the operations, send them to general purpose hardware for execution, and subsequently write-back the execution results to a register file; it essentially replaces the defective execution unit allowing a processor with defective units to be sold or continue operation.

摘要： Embodiments of apparatuses and methods for reducing the uncorrectable error rate in a lockstepped dual-modular redundancy system are disclosed. In one embodiment, an apparatus includes two processor cores, a micro-checker, a global checker, and fault logic. The micro-checker is to detect whether a value from a structure in one core matches a value from the corresponding structure in the other core. The global checker is to detect lockstep failures between the two cores. The fault logic is to cause the two cores to be resynchronized if there is a lockstep error but the micro-checker has detected a mismatch.

摘要： The present document relates to methods and systems for estimating the tempo of a media signal, such as audio or combined video/audio signal. In particular, the document relates to the estimation of tempo perceived by human listeners, as well as to methods and systems for tempo estimation at scalable computational complexity. A method and system for extracting tempo information of an audio signal from an encoded bit-stream of the audio signal comprising spectral band replication data is described. The method comprises the steps of determining a payload quantity associated with the amount of spectral band replication data comprised in the encoded bit-stream for a time interval of the audio signal; repeating the determining step for successive time intervals of the encoded bit-stream of the audio signal, thereby determining a sequence of payload quantities; identifying a periodicity in the sequence of payload quantities; and extracting tempo information of the audio signal from the identified periodicity.
