6711 to 6201

Started by Gautham Mysore October 10, 2002
I've been using using a TMS320C6711 DSK for a few months now. This is the
first DSP that I have ever used. I am going to start using a TMS3206201 EVM
now. I know that the main difference between the two is that the 6711 is
floating point and the 6201 is fixed point so I would have to use q formats.
What are the other differences between the two, especially the differences
that I would have to keep in mind while coding?
When I used the 6711 for real time audio filtering, I used only a mono input
and output stream. I'm not sure if it supported stereo. I have read that the
6201 EVM has a stereo input and a mono output. Is this correct?
Is the programming for the 6201 DMA the same as the programming for the 6711
EDMA? If its different, what are the differences?

Thanks a Lot,
GAutham




Gautham,

I think the biggest difference in the L2 cache. In my opinion this makes the
6711 a much better processor.

Look in the Peripherals reference manual for differences between DMA and EDMA
(EDMA is better).

For certain applications, the L2 cache is a powerful feature. However, for
applications where high I/O bandwidth is required, the C620x series (C6203/4) is
a
better choice. The X-Bus bandwidths (and PCI bus bandwidths of the new C6415)
part
are very high, suitable for video compression and other high data rate
applications.
I/O rates are one of the weak points of the C6711; for example, the part will
not
support off-the-shelf SBSRAMs.

the 6711 can handle fixed point code as well, and the 6711 DSK is a newer
design than the 6201 evm. the 6201 can be faster because it is PCI, but for
the cost, the 6711 can be powerful enough, depending on the application of
course. and yes, the L2 cache makes it more efficient.
