Vector Matrix Multiplication (VMM) is a complex operation requiring large computational power to fulfill one iteration. Resistive computing; including memristors, is one solution to speed up VMM by optimizing the multiplication process into few steps despite the matrices’ sizes. In this paper, we propose an Adaptive Dot Product Engine (ADPE) algorithm based on memristors for enhancing the process of resistive computing in VMM. The algorithm showed 5% error on preliminary results with one on-line training step for one layered crossbar array circuit of memristors. However memristors require new fabrication technologies where the design and validation processes of systems using these devices remains challenging. A comparison of various available circuits emulating a memristor suitable for ADPE is presented and models were compared based on chip size, circuit elements used and operating frequency. |
