Hardware accelerator
The STV0984N is an ultra low power mobile imaging digital signal processor which supports SMIA CMOS color
image sensors up to 2 Megapixel resolution. It performs all the required data processing to deliver good
quality in view finder, still and movie color images.
The STV0984N performs high quality color processing on images, achieving JPEG compression if requested
by Rapido. Further, it includes programmable GPIOs to control external flash LED. STV0984 provides internal
buffering capability along with a versatile clock manager to accommodate different data rates between input
sensors and Rapido interface.
Data is transferred from sensor to STV0984N through Low Electromagnetic Interference (EMI) interface; using
the CCP 2.0 data transfer protocol over LVDS (2 separate CCP 2.0 receivers).
