Differentiating from the legacy Cirrus multi-standard, multi-
channel decoders, this new CS48500 family is still based on
the same high-performance 32-bit fixed point DSP Digital
Signal Processor core but instead is equipped with much less
memory, tailoring it for more cost-effective applications
associated with multi-channel and virtual-channel sound
enhancements. Target applications are:
— Digital Televisions
— iPod
Docking Stations
— Automotive Head Units
— Automotive Outboard Amplifiers
— HD-DVD & Blu-ray Disc DVD Receivers
— PC Speakers
In these applications there are a wide variety of licensable DSP
IP codes available today from:
Cirrus also has developed, or is developing their own royalty-
free versions of popular features sets like Cirrus Bass
Manager, Cirrus Dynamic Volume Leveler, Cirrus Original
Multichannel Surround, Cirrus Virtual Speaker & Cirrus 3D-
Audio.
The CS48500 is programmed using the Cirrus proprietary DSP
Composer GUI development tool. Processing chains may
be designed using a drag-and-drop interface to place/utilize
functional macro audio DSP primitives. The end result is a
software image that is down-loaded to the DSP via serial host
or serial boot modes.
