CA20K1
The CA20K1 VLSI chip is a high performance digital audio processor designed to accelerate digital audio processing. This is Creative's newest class of PCI audio product which includes a complete audio recording and playback system interfaced via the PCI bus. The CA20K1 contains several special-purpose processing units, including:

  • Sample rate converter engine
  • Digital delay line accelerator ("tank engine")
  • Digital filter engine
  • A powerful mixer
  • Microprogrammable audio DSP
  • Various digital I/O capabilities
  • Bus mastering external memory interfaces.

Unlike the host interface control port the bus mastering "audio transport" supports burst mode accesses to the PCI and SDRAM interfaces.
