有用CS497004芯片设计带DTS、DD解码器的吗？

从网上查到了这个发烧级解码芯片的资料和货源，每片220元。如果有坛友做这个就好了。

有熟悉的吗？这个芯片可是顶级解码器上用的。

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 onchip
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 supports the most
demanding audio post processing requirements. It provides an
easy upgrade path to systems currently using the CS495xx or
CS4953x device with minor hardware and software changes.

这个东西好像还要写程序才能用，一般难搞。问下张兄看他能搞吗？

steven.ning 发表于 2010-4-24 13:36

谁送片子？我来整。

rengh 发表于 2010-4-24 14:46

片子厂家送

suyean 发表于 2010-4-24 17:15
