Blackfin Image Processing Toolbox

Product Description

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. It has been highly optimised to be run on Analog Devices’ Blackfin processor family. It is a self-contained software module.

Product also provides C reference codes and wrapper codes for OpenCV like APIs. Along with this demo code is provided to demonstrate the usage of these primitives on Blackfin.

The code has been 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.

  • MIPS measured optimal memory layout, 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.
  • BF527, BF533, BF54x and BF561 supported.
