SigC54xx-SODIMM DSP Module
VoIP Module
Overview
SigC54xx-SODIMM plug-in modules provide multiprocessor DSP solutions for telecom, Internet
routing, and network infrastructure applications. The modular approach to massive DSP
processing offers higher density and performance, lower-cost, and several advantages for
OEM products
Applications for SigC54xx plug-in modules include base-station processing, VoIP (voice-over
Internet protocol) networking functions, VoDSL (voice-over DSL), Internet routing,
multiple-channel speech or audio code / decode (e.g. G.729A or MELP speech compression and
MP3 audio compression), modem banks, echo cancellation, and speech recognition.
The modular approach is particularly well suited to providing a scalable solution for
telecom and Internet equipment applications that require a massive number of DSP devices.

Specifications and Data Sheet
SigC54xx-SODIMM Software Support
The SigC54 plug-in SODIMM modules are supported by Signalogic off-the-shelf DSP software products designed
for DSP-based real-time processing and C54xx DSP code development, including:
- Hypersignal®-Macro and Hypersignal-Acoustic software
series, which offer a number of simulation and real-time instrument functions. Simulation
functions include DSP and math functions, time domain display (including waterfall,
contour, magnitude, unwrapped phase), difference equation, digital FIR and IIR filter
design, sampling rate conversion, frequency zoom, wavelet transform, minimum phase
calculation, and many more. Instrument functions include spectrum analyzer, digital
oscilloscope, stimulus & response measurement, continuous signal generation,
real-time; "snap-in"; filtering, continuous disk record and generate, and more.
- DirectDSP®
is a Windows library that provides low-level and high-level calls for user-defined C/C++,
Visual Basic, MATLAB®, or LabVIEW®programs. The DirectDSP API includes low-level hardware control functions such as reset/run/hold, register access,
block memory transfer, DSP executable file download, etc. High-level functions include
waveform file acquire/generate, continuous signal generation and execution of any
arbitrary Hypersignal DSP or math function. DirectDSP includes strip-chart recorder,
digital oscilloscope and digital tape recorder demo program and source code examples.
- The C54xx Source Code Interface and C55xx Source Code Interface contain numerous
C54xx abd C55xx algorithms and functions in source and binary form, such as optimized FFTs,
filters, matrix, transcendental, trig, signal manipulation function, processor and card initialization
and analog I/O examples, etc. These functions form the basis of higher-level software functions and instruments;
modification can be used to customize Hypersignal or DirectDSP software operation. User-defined C routine hooks are
provided for real-time algorithm development. The C54xx and C55xx Source Code Interfaces can be used as a basic
foundation for user-defined real-time DSP systems and products
