SigC54xx-SODIMM 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 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.

• 300 to 480 MIPS performance, depending on processor type

• Three (3) total 100 to 160 MHz C549, C5402, C5409, or C5416 cores, in three (3) 144-pin GGU packages, each with separate 2.5v (or 1.8v) core and 3.3v peripheral voltages

• 128k x 16 or 256k x 16 zero-wait-state external SRAM per core

• Very small form-factor, 2.35" x 1.15"; fits in 72-pin SODIMM socket

• Supported by SigC54xx Development System which is compatible with DirectDSP®, and Hypersignal®-Macro development software (see below)

• 8-bit HPI host-port, TDM / buffered serial port, external interrupt, and reset signals available at module edge

• JTAG signals are chained between DSPs and available at module edge

• multichannel audio CODEC SODIMM modules also available

SigC54xx-SODIMM Software Support

The SigC54 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
