compress and decompress in VisualDSP++

Hi,

I have a large binary file  (about 6MB) that i would like to compress and  include in VisualDSP++ as a binary file .

when application boots up i would like decompress same file.

Is there any tool to compress and decompress in VisualDSP++ ?or any better way to do this?

Thank You,

Sjoshi

  • Hi,

    From the tools perspective, the Loader supports compression using the ZLib compression engine for some of the older Blackfin processors (BF53x), with example decompression DXEs and further information available in the VisualDSP++ installation under "...\Blackfin\ldr\zlib". This is also documentedin the loader and Utilities Manual under 'Loader/Splitter for ADSP-BF53x/BF561 Blackfin Processors'->'ADSP-BF53x/BF561 Processor Booting'->'ADSP-BF531/BF532/BF533/BF534/BF536/BF537 Processor Compression Support'.

    Unfortunately, there is no such support for the newer Blackfins at present, so for those you would need to seek an alternative solution - perhaps someone else may have some suggestions on the forum.
