<p class=MsoNormal style='margin-left:.5in'>Thanks. I knew about the
macros to change the csl register values but I was curious where I could find a
definition of the registers or what they are defined to be (I wanted to get more
information about them beyond the scope of what is shown on the FFT EDMA
lecture notes). SPRU401 really helps. :)<o:p></o:p></p>

Check out slide 33 in the lecture notes. What you will be using is the
"Chip Support Library," or the CSL. Remember in the second lecture
when I mentioned that in the "old days" you would get a header file
that defined all the registers, but now you operate through the CSL. This
defines a whole set of macros to set registers, fields, etc.<br>
<br>
For example, there is the macro EDMA_RSET that allows you to directly access
the QOPT, QSRC, etc. registers.<br>
<br>
EDMA_RSET(QOPT,0x21300001);//32bitshighpriorityTCC0<br>
<br>
See Section 7 EDMA Module in Spru401 (which is available in the help menu from
CCS 3.1).<br>

I'm also having a tough time locating register definitions from the lecture
notes:<br>
<br>
CIPR<br>
QOPT...etc.<br>
<br>
I found the macros in csl_edmahal.h which was not part of the example project.<br>

<p class=MsoNormal style='margin-left:.5in'>Yea, I forgot to time it and fill
in the requirement. Your presumption of course is correct -- We want you
to use QDMA to do it efficiently, but you need not worry about overlapping the
transfers with computations. <o:p></o:p></p>

xx? ~1.7ms*100 or ~48ms*100? I take it you guys want us to get
roughly the first timing requirement using QDMA. <br>

When we first capture the data in ext ram from CCS. The instructions
wants us to create a plot of this data in CCS. How do you do that?
Should we use the Graph function under the view tab? What options should
we use for it?<br>
