I. INTRODUCTION
Bayesian systems find numerous applications in object tracking [1] - [3], source localization [4], video analytics [5] etc.. Also, there is a growing body of evidence that suggests that the neurons in the brain calculate the posterior probability of states and events based on observations provided by the sensory neurons [1]. These systems are usually implemented in software. But for large systems, a real time implementation using software model is not feasible. This mandates the need for hardware implementation and many existing works [6]-[8] have realized the same. Murray [7] has developed pulse based mixed signal neural circuits. Thakur et al. [8] [9] have implemented an FPGA based stochastic design.
