Memristive Circuit of Quaternion Multiplication and Its Application in Aircraft Attitude Computation

Memristor-based in-memory computing has emerged as a promising solution for overcoming the computational bottleneck associated with traditional von Neumann architectures. Despite its potential, there is a notable absence of in-memory computing circuits specifically designed for quaternion operations. In this brief, we propose a novel memristor array-based circuit for quaternion multiplication, enabling efficient in-memory computation of quaternion operations. The functionality is examined through circuit simulations. Additionally, we present the design of a peripheral circuit for the quaternion differential equation, which is crucial for aircraft attitude calculations. Through a comprehensive comparison between circuit and numerical simulations, we validate the correctness and effectiveness of the designed circuits. The application of memristor-based quaternion in-memory computation holds great promise for revolutionizing aircraft attitude control.
