Save Data on external HD

Started by Michael August 16, 2005
Hello everybody

I got the next problem. Does anybody knows if it is possible to save
data on an external hard disk. I use the DSK C6711. Does anybody
knows if I have to use a FPGA to save the data or does the DSP the
whole work. 

If there are any examples please help me

Thanks Michael

TI has an app note on interfacing an IDE interface to one of their DSKs
(maybe the 5510).  It gives the basic hardware schematic and software
driver but no filesystem.  You won't get much performance with the
basic drivers.

Applied Signal Processing has a FAT32 file system and DSK daughtercards
for CF and hard drives.  Data bandwidth depends on the media, but to a
hard drive a 6711 should be able to continuously read 5 Mbytes per sec
and write 1780 Kbytes per sec.  Writes should go to 3-4 Mbytes per sec
in the next release.

The TI and ASP designs use minimal hardware to implement PIO modes.  To
get data rates higher than this would probably require an fpga to
implement UDMA.
