A good starting point for the Davinci™ digital media processors is DVEVM and DVSDK overview.

am using codec engine.I want to know what is the right processure to
create a simple projecf where i want to take speech data through mic.I
want to store it on DDR2 ram just that much!! which header files i
should refer to and sample codes i can refer??????
In reply to rajas more:
DM6446 'encode' demo included in dvsdk should take input from a MIC and encoded in g.711; however, if you look at the demo source code, you have access to the audio buffer (stored in DDR2) and can choose to send it to g.711 encoder or write it to a file, ....

In reply to Constantine:
I can run encode, decode and interface demos. However, When I copy 'encodedecode' directory in the same folder renaming 'test1' and make changes to 'config' files paths and 'make' file Istill get error like " make: *** No rule to make target `test1.cfg', needed by `test1_config/compiler.opt'. Stop." What am I doing wrong?
Its better to be a fool for a minute rather than being foolish and ignorant for rest of the career![*-)]
In reply to virgoptrex:
some of the build scripts assume the same name as the directory for certain files (e.g. encodedecode_config, encodedecode.cfg), you will need to rename these as well. What I normally do is copy the original demos into a different directory and make the original demo directory my working directory; this avoids many headaches such as the one you are running into.
Thanks it worked out well! I tried both approaches
1. Renaming contents in the scripts and renaming the file names (there were several files and numerous script changes in replica of 'encodedecode' folder). Took me like 20 -25 minutes to do this. I wish I could get a good 'replace in files' program in Ubuntu (notepad++???). [:Y]
2. Easier approach of preserving demo's directory - 'acts like master / reference' directory. Then making replica directory 'working' directory without name/script content changes!
Sorry, I am posting this question as a reply since I could not start a new thread.
I was trying to get started on building the DVSDK demo. The getting started guide that came with the kit (DM6467), mentions about editing the Rules.make file (in section 4.6 of the getting started guide) and modify certain env variables.e.g PLATFORM etc.
I found several of these already in place.
I found several discrepancies between what is stated on the guide and what is already there in this file.for e.g. the guide says to point EXEC_DIR to "....."/$(platform)but the rules.make already has en entry for this variable which does not end in the "$platform". Are we supposed to edit and add it at the end ?Also a few other paths are different eg. theLINUXKERNEL_INSTALL_DIR=/opt/mv_pro_4.0.1/montavista/pro/devkit/lsp/ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082 in the rules.makebut the starting guide says it should be set to .... /<home/ useracct>/..... etc.
Is the starting guide (hard copy I got EVM) incorrect ?)
I also got the linkhttp://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_2_00/latest/index_FDS.html I am unsure as to what updates form here that I really need for a "basic" getting started and building the demos.
Any help/advice would be appreciated.
