SHARC plugin examples

Hi,

New to the SigmaStudio and SHARC world.  We're intending to develop a custom plugin (DLM) for specific SHARC processors (currently ADSP-2156x and ADSP-SC589).  I'm going through the Algorithm Designer document, but I read on another thread that there are sample plugins.  I saw reference to SigmaStudio for SHARC v3.12 (which apparently contains example plugins), but all I could find was SigmaStudio for SHARC v2.2 (which does not).  Can anyone point me to the example plugins?

Thanks,

Jeff
