The CS4970x4 DSP family is an enhanced version of the

CS4953xx DSP family with higher overall performance. 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.
