I'm writing my own codec to run on the DSP side of the DM6467T. A year ago, while writing the first version of the codec on a different platform, I ran across something very useful to integrate in the future. The future has arrived. To the best of my recollection, I found it in a C language reference guide. It was a bunch of C library functions that one could call to manipulate buffer (vector) data using assembly language, without having to learn or write the assembly language. A vector multiply-and-accumulate function comes to mind.
I have searched again for this C language reference guide, but have been unable to find it. Please note I was already aware of VLIB and IMGLIB2. I did find DSPLIB in two flavors. It's close, but I can't tell for sure if this is the same thing I ran across before.
QUESTION ONE: For DSPLIB, is http://focus.ti.com/docs/toolsw/folders/print/sprc265.html#Order Options the correct one for the DM6467T?
QUESTION TWO: Where is a C language reference guide nevertheless, for the C language I'm using in CCSv4 to write my codec. If you can help me find this doc, which I'm sure must exist, I'll search it again for the DSP optimized library functions or some reference to them. This may lead me back to DSPLIB, or it may lead me to yet another programming resource.
Thanks very much,
Helmut
P.S. I may use this to code a YUV422SP (semi-planar) to RGB888 (planar) conversion and optionally vice versa, which I do not believe exists anywhere available already. If I'm wrong, please let me know! (Ref: http://en.wikipedia.org/wiki/YUV)
