Data Compression

DATA COMPRESSION (like Zip & Unzip Functionality)

I have been developing application on ARM7 and have found few hurdles in the Transfer of Data from Device to the Computer. As the data is taking more time to transfer and also as it is been transfered by RS232, I am planning to apply Data Compression on both the ends. (ie. Device side and Computer side.)

Has anybody implemented such thing.

Also if a rapid data transfer code if available I would be thankful.

Thanks in advance.

  • What I meant to say was that different kinds of data (e.g. photo, video, audio, executable code, text etc.) require different compression algorithms (e.g. JPEG, MPEG-4, MP3, zip etc.) in order to optimize compression ratio.
    Perhaps you should say what kind of data you are dealing with. Is it text? Is it measurements taken by an ADC stored in binary form? Is it encrypted packets captured on a wireless network? Is it a photo?
