2D Blit and Raster Graphics

Overview

Key Features

• All buffer formats 100% compatible
• Flexible pixel formats (1/2/4/8/16/18/24/32 bpp; any bit width per channel)
• YUV support (packed, planar, 4:4:4, 4:2:2, 4:2:0, progressive, interlaced)
• Dynamic re-configuration of processing units
• Ready to support standards (i.e. OpenWF)
• Optimized for operations without read-after-write dependencies
• Scan directions: 90/180/270° rotation, horizontal/vertical flip
• Multiple layers (alpha blend) with configurable mapping
• Scaling and warping on-the-fly (e.g. windshield correction)
• Image compression and decompression on-the-fly
• Spacial and temporal dithering
• Special safety features
• Various dual display modes and programmable timing generators
• Perspective warping (simple 3D effects = “2.5D”)
• Arbitrary warping (e.g. for lens distortion removal or HuD)
• High quality re-sampling (super-sampling, anisotropic)
• Linear light filtering (improves motion blur and anti-aliasing quality)
• Image compression and decompression
• Programmable FIR filter (blurring, sharpening, etc)
