1. A method comprising:
allocating one or more memory regions of a memory that is accessible to a processor, wherein the one or more memory regions are each allocated to a particular memory image of one or more memory images associated with a first audio decoder; loading the one or more memory images to a multi-way cache; decoding a first audio stream at the first audio decoder and a second audio stream at a second audio decoder; terminating the decoding of the second audio stream at the second audio decoder; and decoding the first audio stream at the first audio decoder after terminating the decoding of the second audio stream.
