CS48520/CS48AU2B/CS48DV2B Family of DSPs, all of
which feature a 32-bit fixed-point DSP engine that
offers dual MACs, making 300 million multiply-
accumulates at the disposal of the designer. Each of
these DSPs is capable of supporting both standard
processing and an array of 3rd party algorithms.
A complete list of all of the available algorithms
supported by these 3 pin-compatible DSP part numbers
is listed on the back of this document.
The CRD-SB30Wx2 has already been cost-
optimized for manufacturability, undergone strict
design for manufacturability rules, is RoHS compliant
and has already passed EN55022 / CISPR 22 / FCC
Class B, Part 15 EMI Testing so there should be no
delay when you are ready to go to mass production.

Every algorithm can be placed completely
customizable signal flow and then compiled,
downloaded, and then optimized in real-time. The
speaker cabinet and drivers can also benefit from
multiband Parametric EQ to assist in flattening the
frequency response as well as notch out resonation
frequencies or peak passive frequencies that have
been impacted by a passive crossover - again in
realtime.

Feature-rich processing and customized signal
flows can be easily developed using the Cirrus Logic
Audio Software Library, which includes both 3rd party
certified application programs and a modular plug-in
environment for easy customization using the DSP
Composer GUI development tool. The framework
includes certified state-of-the-art matrix audio
decoders, virtualizers, speaker equalization
capabilities, & a wide variety of audio enhancement
algorithms.
The CRD-SB30Wx2 is based around the

High-level, well-structured, well-documented
C languange source for the 8051 microcontroller
has been included which works “as-is” with the
provided signal flow. With minor changes, an
entirely new signal flow inside DSP Composer can
be supported by using a powerful new utility
called Micro-Condenser by generating “snapshots”
of all of the various modes inside DSP Composer.
By using the supplied USB Interface MCU Debug
Adapter, with the latest available Keil compiler
(available at http://www.keil.com/c51), the
developer can quickly make changes to
microcontroller code and then download it via the
MCU Debug header.
