Paperback. The continued exponential growth of artificial intelligence (AI) workloads has outpaced the energy-efficiency gains available from conventional complementary metal-oxide-semiconductor (CMOS) scaling, producing a memory wall and a power wall that constrain both data-center and edge deployment of neural networks. Spintronic devices, particularly spin-transfer torque magnetoresistive random access memory (STT-MRAM), spin-orbit torque MRAM (SOT-MRAM), and stochastic magnetic tunnel junctions configured as probabilistic bits (p-bits), offer non-volatility, sub-nanosecond switching, and intrinsic radiation hardness that may simultaneously address these limitations. The purpose of this quantitative quasi-experimental dissertation was to design and evaluate a unified spintronic microprocessor architecture for neuromorphic AI computing and to quantify its energy efficiency, write performance, probabilistic inference capability, and radiation tolerance relative to CMOS baselines. A four-tier multi-scale simulation methodology was implemented, comprising OOMMF and MuMax3 micromagnetic modeling of the Landau-Lifshitz-Gilbert-Slonczewski equation, HSPICE circuit simulation with Monte Carlo process variation, NeuroSim and a custom compute-in-memory (CIM) simulator for array-level analysis, and PyNN/NEST spiking neural network evaluation at the 45 nm technology node, encompassing 2,847 independent simulation runs. Four research questions addressed energy efficiency, hybrid SOT-STT switching, p-bit Bayesian inference, and radiation tolerance, each with preregistered hypotheses and corresponding statistical tests. Results demonstrated a 5.92 improvement in tera-operations per second per watt (TOPS/W) for SOT-MRAM CIM over SRAM CIM (RQ1), a 75.3% write energy reduction with a concurrent 50 endurance improvement under hybrid SOT-STT switching (RQ2), a 13.6 energy advantage of p-bit Bayesian inference over digital CMOS implementations (RQ3), and the maintenance of 93.82% inference accuracy at 10 Mrad(Si) total ionizing dose with a 263 improvement in single-event-upset critical charge (RQ4). A radiation-hardened-by-design spintronic architecture achieved 28.4 TOPS/W-a 3.64 improvement over unhardened SRAM CIM-at a 2.1 MRAM CIM area overhead, with analog-to-digital conversion identified as the dominant remaining energy consumer. These findings provide theoretical, methodological, and practical contributions to the design of energy-efficient, fault-tolerant, uncertainty-aware AI accelerators for terrestrial edge, automotive, aerospace, and space applications.

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to CitiRetail, Stevenage, United Kingdom, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
