Abstract
In a processor system for audio processing, such as voice recognition and text-to-speech, a dedicated front-end processor, a core processor and a dedicated back-end processor are provided which are coupled by dual access stack. When an analog audio signal is inputted core processor is invoked only when a certain amount of data is present in the dual access stack. Likewise the back-end processor is invoked only when a certain amount of data is present in the dual access stack. This way the overall processing power required by the processing task is minimized as well as the power consumption of the processor system.
