Some of these are only guesses. May help understanding what's going on in the code.

EDmac: Engine DMA Controller

HDMAC: H... ? 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): no idea yet. Probably timing related. A debugstring in Ixus30 from this module: "CountOfClient[i] > 0". Writes into the 0xc0f010xx range on SX100.

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)
