Purpose of This Manual

A PC host controls the AD2437 A
USBi(EVAL-ADUSB2EB). This allows SigmaStudio+ to directly discover and control an A
read back registers and monitor performance. Alternatively, the EVAL-AD2437A1NZ is controllable over a SoM in-
terface through an external DSP host device like the SC594. In the default configuration as a main mode, AD2437
digital audio signals interface directly to the ADAU1452 SigmaDSP
2
signals to the A B network.
The evaluation board also supports local-powered sub mode with different jumper settings, where AD2437 digital
audio signals could interface to ADAU1937 audio codec or four microphones with the help of the ADAU1452. In
the sub mode, AD2437 drives clock and frame sync to ADAU1937 and ADAU1452 for transmitting or receiving
data. Four digital MEMS PDM microphones can interface directly with the A

The SigmaStudio+ graphical development tool is the programming, development, and tuning software for the Sig-
2
maDSP, A B, and Sharc processors. Familiar audio processing blocks can be wired together as in a schematic, and
the compiler generates DSP-ready code and a control surface for setting and tuning parameters. This tool allows
engineers with no DSP code writing experience to easily implement a DSP into their design and yet is still powerful
enough to satisfy the demands of experienced DSP designers. SigmaStudio+ links with both Analog Devices evalua-
tion boards and production designs to provide full in-circuit real-time IC control.
SigmaStudio+ includes an extensive library of algorithms to perform audio processing such as filtering, mixing, and
dynamics processing, as well as basic low-level DSP functions and control blocks. Advanced record-side processing
algorithms such as Enhanced Stereo Capture and wind noise detection are included in the standard libraries. Plug-in
algorithms from Analog Devices and 3rd party partners can be added to SigmaStudio+'s drag-and-drop library.
Along with its graphical DSP signal flow development, SigmaStudio+ also includes other features to speed up the
design cycle from product concept to release. SigmaStudio+ includes tools for intuitively setting control registers,
calculating tables of filter coefficients, visualizing filter magnitude and phase responses, generating C header files,
and sequencing a series of controls to ease your transition from SigmaStudio+ to system implementation on your
microcontroller.
