11 / 22 page STn8815P14 Architecture overview 11/22 2.3 Smart imaging accelerator (SIA) The smart imaging accelerator is provided by the image preprocessing module of the SVA. This flexible imaging engine provides real-time, programmable image processing, and features: ● Shot-to-shot performance (with CMOS sensor): – 3 Mpixel, up to 15 image/s, – 5 Mpixel, up to 9 image/s. ● Direct support for smart sensors (CMOS/CCD modules), unlimited resolution (YUV input with JPEG compression). ● Image reconstruction up to 80 Mpixel/s with raw Bayer input. ● With shutter, maximum sensor resolution depends on external SDRAM size and on target shot-to-shot delay. ● Auto-focus control, auto exposure control. ● Automatic white balance, contrast enhancement, brightness control. ● On-the-fly zoom, flash-gun control. ● Noise reduction, gamma correction, image sharpening. ● Ultra-low power implementation. 2.4 Smart graphics accelerator (SGA) The smart graphics accelerator provides an efficient 2D and 3D drawing tool that enables next generation of games and user interfaces while minimizing power consumption. 2D features ● ROP4. ● Line drawing. ● Triangle and rectangle fill. ● Alpha blending bit blit. ● Stretch/scale/rotate/mirror bit blit. ● Gradient color fill (horizontal and vertical). ● Full picture anti-aliasing filter. ● Image resizing. ● Font-expansion and anti-aliasing text drawing. 3D features ● Texture mapping. ● Texture transparency/blending/clamping/wrapping/mirroring. ● Flat and Gouraud shading. ● 16-bit Z buffering. ● Fog and depth cueing. ● Embossed bump mapping texture generation. |
