Product data sheet
7.4 2D Drawing and DMA Engine
7.5 Quality Video Composition Processor
The video processing functions are based on 4- & 6-tap polyphase filters with up to
64 phases. Three 6-tap filter units are used for horizontal scaling/filtering while three
4-tap filter units are assigned to vertical scaling/filtering. For some video formats (e.g.
YUV 4:2:x) the three 4-tap filters can be combined to work as two 6-tap filters.
A 2D rendering and DMA engine (‘2D DE’) is included to perform high speed 2D
graphics operations. Solid fills, three operand BitBlt, lines, and monochrome data
expansion are available. Supported drawing formats include 8-, 16-, and 32-bit/pixel.
Monochrome data can be color expanded to any supported pixel format. Anti-aliased
lines and fonts are supported via a 16 level alpha blend BitBlt. A full 256 level alpha
BitBlt is available to blend source and destination images together. Drawing is
supported to any naturally aligned memory location and at any naturally aligned
image stride, i.e. 16- and 32-bit pixels should be allocated at byte addresses that are
a multiple of 2 and 4 respectively.
The PNX15xx Series Quality Video Composition Processor (QVCP) provides a high
resolution graphics controller with graphics and video processing. The QVCP in
combination with other modules such as the 2D Drawing Engine and the MBS
(Memory Base Scaler) provides a new generation of graphics and video capability far
exceeding the PNX1300 Series family.
QVCP allows composition of 2 layers, and can output in 656/HD/VGA or LCD format
in up to 10-bit per component and up to 81 Mpixel/s.
QVCP contains a series of layers and mixers. The QVCP creates a series of display
data layers (pixel streams) and mixes them logically from back to front to create the
composited output picture. In order to achieve high quality video and graphics, the
QVCP performs the following tasks:
•
•
•
•
•
•
•
edge detect/correct on an input frame that has been software de-interlaced (this
provides future capabilities in case we develop a better core de-interlacer than 3-
field majority select)
horizontal & vertical scaling (on the input image, or on the result of edge detect/
correct stage)
linear and non-linear aspect ratio conversion
anti flicker filtering
conversions from any input pixel format to any non-indexed pixel format, including
conversions between 4:2:0, 4:2:2 and 4:4:4, indexed to true color conversion,
color expansion / compression, de-planarization/planarization (to convert
between planar and packed pixel formats, programmable color space conversion)
luminance histogram collection, during a scaling or de-interlacing pass
note that not all combinations of format conversion with scaling are supported
