Announcement
------------
Samplify Systems announces the availability of Samplify for Windows, a new PC compression application that demonstrates Samplify's unique lossless and lossy compression capabilities for sampled (numerical) data, such as samples from A/D (or for D/A) converters. Samplify for Windows compresses at 10+ Msamp/sec on a 2 GHz Pentium and achieves 2:1 compression on many bandlimited signals, regardless of center frequency. Samplify for Windows demonstrates the performance of Samplify's compression engine, which will be available in FPGAs and DSP chips in 2005.
Samplify for Windows is available for free (full functionality during a
30-day evaluation) and as shareware ($49.95) fromTarget applications include signal capture boards, signal generator cards, medical instruments, test and measurement equipment, wireless sensor networks, signal transfer and storage networks, and high-speed A/D and D/A converters.
Try Samplify for Windows on your PC, to see how well your signals samplify (compress). If you like Samplify's compression results (at
10+ Msamp/sec on your PC), contact Samplify Systems to get identical results using your FPGA or DSP, at sampling rates up to 100 Msamp/sec.Wanted: signals to compress
---------------------------
Samplify Systems is looking for signals to compress: sampled data from A/D (or for D/A) converters, streams of numbers, matrices, etc. that aren't currently being compressed, to determine how well Samplify compresses such signals. Samplify will compress "traditional" sampled data, such as speech (PCM, 8 ksamp/sec), audio (WAV, 48 ksamp/sec), and image (TIFF) files, but such signals already have effective compression solutions (ADPCM, MP3, WMA, JPEG, etc). Instead, Samplify is targeting high-speed sampled data signals that haven't been compressed (or compressible) before.
Samplify compresses streams of numbers (integers) that represent real-world signals, signals for which no effective compression solutions have been available. If the following bullets describe your signals and/or systems, please try Samplify for Windows:
=B7 You would save money by reducing signal storage or network traffic bottlenecks =B7 You've never tried to compress your signals before =B7 You work with bandlimited (oversampled) signals, where the sampling rate is at least two times higher than your signal bandwidth =B7 Your sampling rates are reasonably high (5+ Msamp/sec) =B7 You system already contains an FPGA (Xilinx, Altera) or DSP (TI, ADI, Freescale) in the signal processing path, or you are planning to use FPGAs or DSPs
After trying Samplify for Windows, please send us an e-mail ( snipped-for-privacy@samplify.com) describing your signals, and let us know what kind of compression ratio or rate-distortion curve you got using Samplify for Windows, and whether you plan to use lossless (SignalZIP) or lossy (Samplify, NoiseTrak) compression.
