Blackfin 2D Graphics Library (BF2DGL-OCV)

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.

  • Target Processor: This software module supports ADSP-BF52x, ADSP-BF53x, ADSP-BF54x, ADSP-BF561 processor families on VisualDSP++ 5.0 U7. Demonstrations are available for ADSP-BF527, ADSP-BF533, ADSP-BF548 and ADSP-BF561 EZ-KIT Lites.
  • Note that there is no demonstration code for ADSP-BF535/ADSP-BF537. The library should work on all Blackfin processors, but it has been tested on ADSP-BF527, ADSP-BF533, ADSP-BF548 and ADSP-BF561.
  • Input format: ARGB-8888 format, alpha (A) represented in only 7 bits Most significant bit is sign bit and it is always 0.

Notes:

t = thickness of the primitive.

Measurements done with CAS = 3 for SDRAM, CCLK = 513 MHz for BF527, BF533 and BF548, 600 MHz for BF561 and SCLK = 128 MHz for BF527, BF533 and BF548, 100 MHz for BF561.

In Memory scheme 1, Instruction and Data cache is enabled. The cache is set in "write back" and "large cache" (DCBS=1) mode. In Memory scheme 2, cache is disabled and some codes and data are in on-chip L1 memory while rest is in off-chip L3 memory.

One channel Memory DMA is used.

Performance data are dependent on the dimensions of the primitives.

Code memory (KiB) Data Memory(KiB) Overlay Buffer Frame Buffer
58 474 Depends on display size. Depends on display size.

  • 1 KiB = 1024 Bytes.
  • Each overlay buffer will be of size DISPLAY_WIDTH X DISPLAY_HEIGHT X 4.
  • Each Display buffer will be of size DISPLAY_WIDTH X DISPLAY_HEIGHT X 3 for LCD display and CCIR_WIDTH X CCIR_HEIGHT for TV display.
  • DISPLAY_WIDTH = 480 for ADSP-BF548, 320 for ADSP-BF527 and 720 for ADSP-BF533/61
  • DISPLAY_HEIGHT = 272 for ADSP-BF548, 240 for ADSP-BF527 and 576 for ADSP-BF533/61
  • CCIR_WIDTH = 1728 for ITU-R BT.656.
