Developing or using a S3C2410X Delta driver would likely involve:
The primary challenge in implementing VIS on this platform is resource contention. The S3C2410x has limited internal cache and relies heavily on external SDRAM. High-resolution graphical interfaces consume significant memory bandwidth. When the processor is fetching large graphical buffers for the display, it may starve the UART handler responsible for talking to the Delta driver. -vis On S3c2410x Delta Driver -
The (an ARM920T-based microcontroller by Samsung) integrates a Camera Interface (CAMIF) and a post-processing unit known as Delta . This Delta unit is designed for real-time Video Image Surveillance (VIs) . Unlike standard video capture drivers (e.g., s3c2410-camif ), the Delta driver implements Hardware-Accelerated Motion Detection . It compares consecutive image frames (or a reference frame against a live frame) and generates a delta map (difference bitmap) without CPU intervention.
