The CS4970x4 DSP family is an enhanced version of the
CS4953x DSP family with higher overall performance. In
addition to all the mainstream audio processing codes in on-
chip ROM that the CS4953x 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 will support the
most demanding audio post processing requirements. It is also
designed as an easy upgrade path to systems currently using
the CS495xx or CS4953x device with minor hardware and
software changes.
