In-Memory computing has drawn many attentions as a promising solution to reduce massive power hungry data traffic between computing and memory units, leading to significant improvement of entire system performance and energy efficiency. Emerging spintronic device based non-volatile memory is becoming a next-generation universal memory candidate due to its non-volatility, zero leakage power in un-accessed...
In this paper, a key-controlled hybrid spin-CMOS polymorphic logic gate using a novel 5 terminal magnetic domain wall motion device is proposed. The proposed hybrid polymorphic gate is able to perform a full set of 2-input Boolean logic functions (i.e. AND/NAND, OR/NOR, NOT, XOR/XNOR) by configuring the applied keys. The SPICE device-circuit co-simulation indicates that a full adder design using our...
Polymorphic gates are capable of adapting to multiple functionalities depending on the application and need. In this paper, we propose a hybrid spin-CMOS polymorphic logic gate based on a novel 6 terminal composite magnetic domain wall motion device structure. As far as we know, we are the first to present a single polymorphic gate that is able to perform a full set of 2-input Boolean logic functions...
Approximate Computing as a promising approach in Digital Signal Processing applications has been extensively analyzed to trade off limited accuracy loss for improvements in other circuit metrics, such as area, power, and speed. Most previous works on approximate circuit design have hardwired the degree of approximation in their implementations. This significantly limits their applicability, since...
