Overview
The Silvertip brings Analog Devices ADSP-2106x SHARC DSP floating-point power to a
low-cost, very small form-factor ISA or PC/104 bus platform. This standard-size
PC/104-format board includes SHARC processor that can operate with host computer or
stand-alone via onboard boot FLASH. An expansion connector extends a portion of the SHARC
processor bus to additional I/O or memory devices.
Using DirectDSP®; software, the onboard host interface provides direct access from
C/C++, MATLAB, Visual Basic and LabVIEW host environment under Win9x and Windows ME to the
SHARC processor's IOP registers and DMA-driven host port (Windows 2000 support is in
progress). Host PC programs in these popular environments can reset and boot the SHARC,
download COFF files (executable DSP code files), read/write offchip and onchip memory,
perform symbolic debug, integrate board and processor attributes and properties, and set
up real-time or streaming digital I/O. Read and write access to the SHARC's internal SRAM
can occur while the SHARC's DSP core is operating, without requiring the processor to
stop.
The Mini-Bus expansion connector extends serial ports and a subset of the SHARC's
external processor bus for 32-bit access to memory-mapped devices. It has two (2)
full-duplex synchronous programmable serial ports, a single bi-directional SHARC link
port, processor flag I/O, and SHARC IRQ inputs.
Silvertip PC/104 Software Support
The Silvertip is fully supported by Signalogic's
Hypersignal®-Macro
and Hypersignal-Acoustic software packages. In addition, both the
board and Hypersignal packages can also be used with DirectDSP®,
which offers C/C++, Visual Basic, and MATLAB® programming interfaces. Used in conjunction
with the Silvertip, the Real-Time Composer™/Hypersignal software combination provides sophisticated
DSP-based instrumentation, visualization and display of waveforms, block-diagram based
automation of development and test sequences, and numerous tools for all levels of DSP
product, system, and algorithm development. The complete range of DSP/math functions,
interactive waveform display and editing, difference equations, filter design, and
real-time code development facilities offered by the software is fully active with the
Silvertip. Display examples include interactive frequency domain waterfall and contour
(joint time-frequency), .WAV display, pole-zero, unwrapped phase, and group delay.
Additionally, the ADSP-2106x DSP Source Code Interface allows
real-time code to be designed, simulated and developed for the SHARC, and results
downloaded, tested and graphically debugged in real-time with the Hypersignal
software package.
