[OT] SDRAM ADC Data Compression on Embedded System

Alex Ruiz

Hallo

This is quite Off Topic, but just in case someone have had experienced it.:

I'm working on a project using AT91SAM9260 @ 180MHz that as 64MB of SDRAM to store ADC acquisition using a File System.

The acquired data is send over a TFTP session. It takes about 82 seconds to send 30MB of data.

I'm considering using a compression algorithm in order to reduce the volume of information and consequently the amount of time to send it.
I found a lot of open source stuff but they all apply to x86 PCs running @ > 1GHz.

I'm afraid of ending up taking more time to execute the compression algorithm than to send the compressed data itself via TFTP.

Have anyone used data compression on Embedded System, especially in this case where I cannot afford information degradation?

Any information would be very appreciated.
