This is a demo program of the paper L. Ma, J. Tian, and W. Yu, "Visual saliency detection in image using ant colony optimisation and local phase coherence," Electronics Letters, Vol. 46, Jul. 2010, pp. 1066-1068.

This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL).The step-wise...
