In addition to all the mainstream audio processing codes in on- chip ROM that the CS4953xx DSP offers, the CS4970x4 device family also supports the decoding of major high-definition audio formats. Additionally, the CS4970x4, a dual-core device, performs the high-definition audio decoding on the first core, leaving the second core available for audio post-processing and audio enhancement. The CS4970x4 device supports the most demanding audio post processing requirements. It provides an easy upgrade path to systems currently using the CS495xx or CS4953xx device with minor (or no) hardware and software changes. Ordering Information See page 27 for ordering information.
