Product Details
Blackfin Image Processing Toolbox is a set of image processing primitives designed to enable faster development of complex image or video processing solutions on Blackfin. Primitive functions have been highly optimized to run on Analog Devices’ Blackfin BF-5xx and BF-60x processor family. It is a self-contained software module. The library is MISRA-C compliant.
Product also includes C reference codes for the primitives and wrapper codes for OpenCV like APIs. Along with this demo code is provided to demonstrate the usage of these primitives on Blackfin.
Code is implemented such that it is able to work on images that are both in L1 and L3 (external memories like SDRAM/DDRAM) memory. Memory movement APIs help in moving data from L3 to L1 and back through MDMA.
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.

- MIPS measured optimal memory layout, on ADSP BF533
- For the optimal memory layout, all code and data used by the module was L3 cached and the input/output buffers were filled using MDMA memory
- "Data RAM" for one instance, includes Stack, Scratch, Instance/Stage, Minimum Input and Output Single Buffers
- 1 KiB = 1024 Bytes
- ADSP-BF561 supported for VisualDSP++5.1.1 project and ADSP-BF533, ADSP-BF609 and ADSP-BF707 for CrossCore Embedded Studio 1.1.0 projects
