Does anyone have experience of processing speech test vectors on the

DSK using RTDX?
Using the usual fread and fwrite functions to do
File I/O is extremely slow
and the help in Code Composer Studio is not very
clear for RTDX although I
am fairly certain this is the way to go.
There must be a way to speed up the data transmission between the host and
the target - if anyone has found this and tried it successfully then I
would
be interested,
thanks

Andy,
The std io functions are very slow and you want to stay away from them
totally if you need any performance at all. They are only useful [in my
opinion] for development and debug. Standard JTAG RTDX is probably one to two
orders of magnitude faster. If you are fortunate enough to have an XDS560,
HSRTDX is even faster.
I have used RTDX for information logging but I did not measure the data rate
- but it blew the doors off of std io.
