2D Graphics Primitives, Blackfin
2D Graphics Primitives, Blackfin
The 2D Graphics Primitives (BF2DGL) library for the Blackfin processor implements primitives, which are based on the Open GL-ES/OpenCV APIs and are supported with wrapper example code for the OpenGL-ES/OpenCV, GLUT, and extended APIs.

Product Details
The Blackfin 2D Graphics Library (BF2DGL) 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. All the primitives can be drawn in ARGB format while a limited set of the primitives is also supported in UYVY format. The primitives are based on Open GL-ES/OpenCV APIs and they are supported with wrapper example code for OpenGL-ES/OpenCV, GLUT and extended 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.
Licensing
Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.
