Product Details

The Video Content Analysis Toolbox (VCAT) Library for the Analog Devices Blackfin processor is an implementation of video analytics tools to be used in video surveillance for detection of events such as intrusion detection, left/removed object detection. The tool supported now is Foreground Objects/Blob Detection in video captured from a stationary camera. The C-callable API’s are flexible and designed for Video Surveillance use cases.

  • MIPS measured using sequences where detected objects cover around 30% of the scene, optimal memory layout, PAL D1 input running on ADSP-BF561 rev 0.5 processor.
  • Measurements done with CAS = 3 for SDRAM, CCLK = 600 MHZ, SCLK = 100 MHZ for ADSP-BF561
  • Data cache and instruction cache are enabled. The cache is set in "write back" and "small cache" (DCBS=0) mode. Memory DMA is used with 32 bit DMA.
  • "Data RAM" for one instance, includes Stack, Scratch, Instance/State for D1 resolution.
  • "Frame Buffer" for one instance of D1 PAL (720x576) resolution.
  • All "Scratch" and "State" Memory are for D1 resolution.
  • 1 MB = 1024 KiB; 1 KiB = 1024 Bytes.

NOTE: In deriving the "Moving Average Peak" value, an 8 consecutive frames sliding window was used. An average cycle count was measured for each window of frames, and the worst case average cycle from all sliding window measurements was determined to be the "Moving Average Peak" value.
