Information processing applications related to associative computing like image/pattern recognition consume excessive computational resources in the Boolean processing framework. This motivates the exploration of a non-Boolean computing approach for such applications. In this work, we demonstrate: (i) novel hybrid set of pair-wise coupled oscillators comprising of vanadium dioxide (VO 2 ) metal-insulator-transition (MIT) system integrated with MOSFET; (ii) degree of synchronization between oscillators based on input analog voltage difference; (iii) implementation of hardware platform for fast and efficient evaluation of L k fractional distance norm (k<;1); (iv) improved quality of image processing and ~20X lower power consumption of the coupled oscillators over a CMOS accelerator.
