Magnetic Priority Encoder Based on Spin Devices
Abstract: Energy dissipation has already become an important consideration in the design of digital integrated circuits. Because current-induced domain-wall (DW) motion is a common switching mechanism, high-density, low-power, and high-speed circuits are possible. Because spin computing is one of the most common sources of energy dissipation, employing spin logic to design digital circuits is an effective way to reduce the circuit's energy dissipation. As a result, a new spin-based priority encoder …
