Multicore audio DSPs tout low cost, high performance

What is a DSP?
Digital signal processing; The study of signals in a digital representation and the processing methods of these signals; Digital signal processor; A specialized microprocessor designed specifically for digital signal processing, generally in real-time.

What are multicore devices?
A microprocessor that combines two or more independent processors into a single package or IC. Multicore chips allow for greater increases in computing power as compared to a single CPU continually made to run faster. In general, multicore microprocessors allow a computing device to exhibit some form of thread-level parallelism (TLP) without including multiple microprocessors in separate physical packages. This form of TLP is often known as chip-level multiprocessing.
