DSPInterfaceHeaderconnectedtoCRD-USBMASTER-DC-Zdaugtercard
connected via JP1 ribbon cable enables real-time control of the DSP
parameters shown in the DSP Composer .CPA signal flow file
The CS48520/CS48AU2B/CS48DV2B DSP Family
is programmed using the Cirrus Logic DSP
Composer ? proprietary GUI software development
tool. An audio signal processing chain is designed
using a drag-and-drop interface. The tool then
configures the DSP through the SPI ? /I 2 C ? serial
port via the supplied CRD-USBMASTER-DC-Z
daughter card which is connected to the PC via
USB 2.0 cable.
MICROCONTROLLER PROGRAMMING SIMPLICITY
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

The supplied USB to 8051 Debug Dongle is connected to MCU Debug
Header. This connection enables a real-time, in-circuit control & debug of
the 8051 family C microcontroller code as well as upgrading of the
connected SPI Flash image generated by Micro-Condenser
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.
