• Linear and block-based (4x4 pixels) frame buffer modes
• Fast buffer clears:
— Write large bursts of buffer clear data to the system memory from the bus interface unit without
the aid of the 2D/VG rendering pipeline
• Support for OpenVG render to Image
31.1.2.2 2D bitmap graphics (separate 2D unit)
• Parallel operation with the 3D pipeline, independent command input
• BitBlt (surface-to-surface copy)
— Format conversion from monochrome/ARGB/YUV to ARGB during BitBlt
• Block fill
• Internal 32-bit color precision
• Source bitmap format:
— 1/4/8-bit monochrome
— ARGB4444, RGB565, ARGB1555, ARGB5551, ARGB8888
— Programmable ARGB order: ARGB, BGRA, ABGR, RGBA
— Packed YUV 4:2:2 formats (FOURCC codes YUY2, UYVY, YVYU), two pixels per 32 bits
of data
— 1-bit bitmap maps to foreground and background colors
— 4-bit bitmap is optionally gamma corrected to 8-bit alpha values and can be combined with
foreground color to draw anti-aliased fonts
• Destination bitmap format:
— ARGB4444, RGB565, ARGB1555, ARGB5551, ARGB8888, B8, A8, AB88
— Programmable ARGB order: ARGB, BGRA, ABGR, RGBA
• Supports three source bitmaps for separate mask/pattern/alpha bitmap support plus reading
destination for ROP, blend and color key operations
• Supports masking source coordinates for wrapping patterns
• Supports ROP4 (ROP3 with separate ROPs for masked and unmasked pixels) logical operations
• Supports inverting mask and alpha values from source
• Supports destination rotation by 0/90/180/270 degrees
• Supports programmable blending with optional alpha inverse premultiply
• Supports per pixel and constant alpha with optional modulation by source color alpha for OpenVG
alpha masking
• Supports color keying by source and destination colors, with optional ignoring of alpha channel
• Supports one scissor rectangle for destination coordinates
• Dithering (ordered)
• Color component masking
• RGB reads and writes
