Press Release for SigC54xx-PC/104
Telecom and Internet Equipment in Small PackageDALLAS, TX (March 1, 2000)— The SigC54xx-PC/104 board uses a module approach to provide up to 4800 MIPS in a single PC/104 form-factor footprint. The board accepts modules with Texas Instruments C54xx DSP processors and modules with 16-bit audio and speech analog I/O. It is suitable for embedded telecom and Internet infrastructure applications where space is at a premium. The SigC54xx-PC/104 board has four (4) SODIMM module sites, two on each side, which accept the processor and/or analog I/O modules. Available processor module types include the SigC5420-SODIMM with six (6) Texas Instruments C5420 processors (200 MIPS each), and SigC549-SODIMM with three (3) C549 processors (100 MIPS each) and three (3) 128k x 16 SRAM devices. Also available is the SigSD4-SODIMM module with 4-channel 16-bit sigma-delta analog I/O. The Texas Instruments C54xx DSP family offers high performance, low power consumption, and extremely small size. It is widely used in applications such as voice-over-Internet, audio-over-Internet, cellular communications, and base-station processing. In these applications, the C54xx is often used to perform speech compression, MPEG Audio (MP3), echo cancellation, modems, and other numerically intensive functions. Expansion "mezzanine" boards are available for the SigC54x-PC/104 board, including 2M x 32 SRAM board and digital I/O and analog I/O boards. Expansion boards use the dedicated, high-speed "Global Bus" expansion connector, to provide optimum performance for real-time systems. The SigC54x-PC/104 board is supported by Hypersignal software. The DirectDSP® software provides programming interface from C/C++, MATLAB, LabVIEW and Visual Basic. From these languages, DirectDSP offers low-level functions such as reset/run/hold register access, board configuration and interrogation, block memory transfer, and DSP program (COFF) file download. High-level functions include waveform file acquire/generate, continuous signal generation and execution of arbitrary Hypersignal DSP or math functions. Real-Time Composer™ is a Windows program that allows block-diagram simulation and interactive display and instrument functions, including control over individual Hypersignal and MATLAB blocks. The Hypersignal®-Macro and Hypersignal- Acoustic software support the SigC54xx-PC/104 board with simulation and real-time instrument functions, including DSP and math functions. C54xx Source Code Interface software contains numerous algorithms and functions in source and binary form and can be used as a basic foundation for user-defined DSP systems or products.
