Description
===========
DM6437 iUniversal Demo

The purpose of this application note is to explain the principles of developing 
and optimizing a DSP Video Analytics application in an iUniversal codec engine 
framework using the TI Video Analytics Library 
(VLib, http://www.ti.com/vlibrequest). The algorithm used as the example is 
the Canny Edge Detector. 

In addition it will show how to develop the algorithm as an XDM Compliant codec 
using IUNIVERSAL interface to Codec Engine. Developing the algorithm in this way 
allows us to write a single C64x+ core algorithm that can be used on either a DSP 
only device such as the DM6437 or on an ARM+DSP device such as the DM644x, 6467 
or OMAP35xx. The following article aims to provide a worked example. It should 
be read in conjuction with this iUniversal article. 

The Canny Edge Detection algorithm will be used to illustrate how to architect the 
DSP software to break down an image processing algorithm based on large frames of 
data into slices where possible. Using slices allows optimal use of the small but 
fast internal memory available on these devices to improve performance.
