Product Details

The Blackfin 2D Graphics Library (BF2DGL-OCV) is a collection of Graphics primitives to help solve the Graphics rendering problem of ADI-Blackfin users. These primitives have been optimized to run on the Analog Devices’ Blackfin BF-5xx processor family.

The primitives are based on OpenCV APIs. A demonstration code is also provided to demonstrate the usage of the various graphics rendering primitives on Blackfin.

The module contains a standard C-callable API. The code has been implemented using Instruction Cache, Data Cache and Memory DMA to optimize the graphics rendering performance.

Features

  • Line: Horizontal, Vertical and of any slope.
  • Polyline/Polygon: Supported.
  • Rectangle: Draw & Fill Rectangle.
  • Circle/Ellipse Draw and Fill
  • Circular Arc/Elliptical Arc.
  • Chroma Key/Tex Rendering.
  • Alpha Blending of overlays.
  • Per pixel Alpha blending supported.
  • Dirty Sync Operation: Supported.
  • Color format for Drawing: ARGB, UYVY.
  • In Color format UYVY only lines, rectangle draw/fill and text are supported.
  • Real time Application to demonstrate usage of ePIXC for blending & color conversion using Graphics primitives on ADSP-BF609.
  • Cache: I Cache & D Cache in Release and Debug mode.
  • MDMA: One channel Memory DMA is used.
  • Real time demonstration supports both ITU-R BT.656 (for TV) and RGB888/BGR888/RGB565 (for LCD) output formats.

  • t = thickness of the primitive.
  • Measurements above for projects on CrossCore Embedded Studio. For more details on cycle counts on ADSP-BF561 on VisualDSP++ 5.0, refer the Product Specs.
  • One channel Memory DMA is used.
  • Measurements done with Anti-aliasing enabled.
  • Performance data are dependent on the dimensions of the primitives.
  • BF561 supported for VisualDSP++5.0 Update 10 project and ADSP-BF527/ADSP-BF533/ADSP-BF609 for CrossCore Embedded Studio 1.0.2 projects.
