HELLO, I may describe my problem again. I m working on TMS320C6711 DSK. I have to transfer digital data & not analog from Music CD or any file saved in HDD(44.1 kHz+16 or 24 bit) through Parallel port (or any other option) as the audio-codecs/data codec of the card do not support digital data input. Then have to perform 4 operations: 1-Interpolation: 44.1->88.2 2-Decimation: 88.2->44.1 3-SRC for Rational Factor: 44.1->48 4-Multistage SRC: 44.1->192 I have to program this DSK to function as a preamplifier and listen to the audio after all the above operations r performed on the DIGITAL AUDIO INPUT. Then transfer that data back to PC(HDD) through Parallel port(or any other option). The "ti\examples\dsk6711\bios\audio\audio.pjt" example described in "http://focus.ti.com/lit/an/spra598/spra598.pdf" deal with analog audio & not digital audio. And http://www.yahoogroups.com/group/c6x is not active & only 55x group is coming up with messages. My logical solution to the problem: 1a)Transfer a file from PC(HDD) through HPI to DSp's memory space (using dsk6x11hpi.h) BUT I couldn't find "WINDOWS.H" anywhere in my PC. 1B)Transfer a file from PC(HDD) through EDMA to DSp's memory space 2)Transfer that file from DSp's memory space to McBSP (better) or EMIF as i have to perform many operations. 3)Through EDMA back to PC. Wanna listen to ur suggestions & any other easy/suitable solution with some TI's docs regarding that. regards. |
