hi:
 i want to get dct4x4 transform in 55x dsp. And I get some useful information from the document " TMS320C55x Hardware Extensions for Image/Video Applications Programmer’s Reference".------you can get it from internet easily.
the document explain how to get dct8x8 transform result step by step.i have tested it !right.
 In page 2-5 , it tell me some information about how to get dct4x4 tranforme result.but it is
so obscurity that i can't understand how to use it!!
 who can give me hands! thanks.

Hello,

 Probably, the c55x image library would be your good reference.

 1) Download the library
 http://focus.ti.com/docs/toolsw/folders/print/sprc101.html

 2) Example
 - .. \c5500\imglix\examples\dctidct

 Best Regards,
 Ishigami
