Title (EN) MULTI-CORE AUDIO PROCESSOR WITH DEADLINE SCHEDULER
(FR) PROCESSEUR AUDIO MULTICŒUR AVEC PROGRAMMATEUR DE DATE LIMITE
Abstract:
(EN) A multi-core audio processor includes a plurality of audio processing cores having differing capabilities, a plurality of buffers, wherein each buffer is configured to store a plurality of samples associated with a corresponding audio stream, a deadline scheduler including a plurality of deadline registers configured to store a plurality of deadline values for each audio stream, and a plurality of audio processing core interfaces coupling the plurality of audio processing cores to the deadline scheduler, each of the audio processing core interfaces associated with a corresponding audio processing core. The plurality of deadline values indicate an order of processing of samples stored in the plurality of buffers by the plurality of processing cores.
(FR) L'invention concerne un processeur audio multicœur comprenant une pluralité de cœurs de traitement audio ayant des capacités différentes, une pluralité de tampons, chaque tampon étant configuré pour mémoriser une pluralité d'échantillons associés à un flux audio correspondant, un programmateur de date limite comprenant une pluralité de registres de date limite configurés pour mémoriser une pluralité de valeurs de date limite de chaque flux audio, et une pluralité d'interfaces de cœurs de traitement audio couplant la pluralité de cœurs de traitement audio au programmateur de date limite, chacune des interfaces de cœurs de traitement audio étant associée à un cœur de traitement audio correspondant. La pluralité de valeurs de date limite indiquent un ordre de traitement d'échantillons mémorisés dans la pluralité de tampons par la pluralité de cœurs de traitement.
