Some of these are only guesses. May help understanding what's going on in the code.
EDmac: Engine DMA Controller BltDmac: DMA related to image data? SSG (source module, task): Synchronization signal generator for the sensor / its driver (explanation found in a Hitachi datasheet) TG (task): Sensor drive-pulse (timing) generation (explanation found in a Hitachi datasheet) PCEvf (source module): Live view over PTP (utilizes MJPEG compression). Only present in models with official PC remote control feature. Pwrcnt (source module): Power control? A debugstring in Ixus30 from this module: "CountOfClient[i] > 0". Writes into the 0xc0f010xx range. BrtDrv (source module): brightness driver (S1 IS debug string, (live?) image processing related) BrtMsr (~source module): brightness measure BrtWei (~source module): brightness weight BrtCrct (source module): brightness corrector WBinteg: white balance integral ("integ" seems to stand for integral usually)
Angel (source module): has something to do with color adjustment, see for example: http://chdk.wikia.com/wiki/30Duseful things can be found near "getpropertyfromcase error" strings
