An eight element linear iris excited centered broadwall waveguide slotted array antenna is realized at 10GHz using FEM simulator. Different feeding arrangement is illustrated with proper electric field magnitude and phase distribution for obtaining higher gain and lower first side lobe level. 15.01dB gain with zero beam tilt and −14.89dB side lobe level is achieved in center fed case with 2.88dB improvement...
Normalized electric field along the slot length for different depth of iris is studied at 10GHz in this paper. Resonance length is obtained as 15mm for which electric field symmetry is observed. Thick iris-slot combination is studied with reassigned mesh to obtain perturbation of slot field at certain depth of iris. From the slot voltage calculation slot excitation is found to be at 5.3mm depth of...
Rate Monotonic Scheduling is one of the well known fixed-priority driven scheduling algorithms for real time systems. However, not many well known real time operating systems directly provide this scheduler, although almost all of them provide some form of pre-emptive, priority driven scheme. The design of any real time system hinges on time being considered as one of the important design parameters...
This work presents modeling of the self-heating effect in Spin Torque Transfer RAMs (STTRAM) and analyzes its impact on the functional reliability. We perform computational fluid dynamics based 3-D thermal simulation in Fluent?? for STTRAM at 90 nm technology and characterize the thermal profile considering write condition. The thermal analysis is connected to device and circuit simulators to estimate...
In this paper, we investigate the combination of a novel computing paradigm referred to as Memory Based Computing (MBC) and an emerging non-volatile nanoscale memory technology, namely Spin-Torque Transfer Random Access Memory (STTRAM), to build a reconfigurable nanocomputing framework with high integration density, robustness and energy-delay efficiency. MBC uses a 2-D memory array as underlying...
Use of two-dimensional memory array for lookup table (LUT) based reconfigurable computing frameworks has been proposed earlier for improvement in performance and energy-delay product (EDP). In this paper, we propose an integrated solution for achieving significantly higher EDP in these frameworks by leveraging on the read-dominant memory access pattern. First, we propose to employ an asymmetric memory...
