C67XX Comparison for M.S. Thesis

Hi all,

I'm in the process of writing a thesis for a M.S. in electrical engineering.  Over the past few years I've developed a DSP processor in FPGA for space flight.  The primary reason for doing this was there had been no other viable option.  This is no longer true with TI's release of a space qualified C6701.  In light of this, I would like to do a comparison against my custom processor and the C67XX.  I've found a few benchmarks for performance here

TMS320C67X Assembly Benchmarks at Texas Instruments

This does not include two additional pieces of information that I'm looking for.  

1) The number of gates used to implement the C67XX core

2) The number of cycles needed to "unscramble" the result of simultaneously computing two real FFTs with one single complex FFT computation.  This would assume the buffer to be "unscrambled" has already been bit reversed.

3) Approximate release date of the space qualified C67XX class of processors.

The second one would be nice to have, but I really do need the first to do a proper comparison.  So far I believe the C67XX architecture to be twice as fast as my implementation, but to use approximately 4-8 times the gates with all the execution units (no proof yet).

Thanks,

Brian Mokrzycki

 

  • Brian,

    We'll look into whether or not we have this information. Unfortanately, the C6701 was created a long time ago (although only recently qualified for space), and so I am unsure if we still have documentation that you have asked for.

  • Brian,

    We have some documentation on the C6701-SP space qualified info you requested, please email me at holcombe@ti.com and i'll get the documents to you.  Fyi...the C6701 space qualified version was released in 2003.  We are currently working on a space qualified version of the C6727 DSP.
