Abstract: Methods and systems for accessing protected memory are disclosed. Aspects of one method may include enabling access to protected memory on a chip when a user access key for the chip matches a customer specific access key that is pre-programmed and stored in a one-time programmable memory within the chip. The protected memory in the chip may comprise non-volatile memory. Portions of the protected memory may be allocated for access by different users. Accordingly, each user may have a different user access key to access the portion of the protected memory allocated to that user. A user may use offset to objects when sending commands to access the protected memory. The object may indicate memory address and data size. This may allow a level of abstraction where a customer may not need to know specific addresses for the portion of the protected memory being accessed.

Abstract: Methods, systems, and apparatuses are described for performing acoustic echo cancellation with internal upmixing that allow for a more effective handling of acoustic echo cancellation of audio components that are provided via different channels. In an embodiment in which audio is played back using two loudspeakers, audio components that are panned equally among the loudspeakers form a “phantom center image.” Acoustic echo cancellation is performed by initially upmixing the different channels to internally create modified versions of these channels and a virtual channel representative of the phantom center image. Each of these channels is passed through a respective adaptive filter that is configured to estimate an acoustic echo produced by each respective channel. These estimates are then subtracted from the signal received from one or more microphones (or from a signal obtained by combining multiple microphone signals) to suppress or eliminate the acoustic echo.
