Data Buses
Published in Mike Tooley, Aircraft Digital Electronic and Computer Systems, 2023
Within the LRU, the dedicated digital logic and microprocessor systems that process data locally each make use of their own local bus system. These local bus systems invariably use parallel data transfer, which is ideal for moving large amounts of data very quickly, but only over short distances.
GMMSO: game model-combined improved moth search optimization approach for reconfigurable asymmetric multi-processor system-on-chip architecture
Published in Engineering Optimization, 2023
Isaivani Mariyappan, Malathi Veluchamy
The proposed strategy follows the AHt-MPSoC framework for consideration, and the course-grained HWAs in the system execute application-specific instructions. The MILP scheme is implemented for design space exploration to identify the best configuration set-up (Dammak, Niar, and Abid 2013; Dammak et al.2015). The divergence state estimation with biogeography-based optimization (DSEBBO) technique is proposed in the AHt-MPSoC framework by considering the HWA sharing methodology and improving the system performance metrics in less time (Mariyappan, Malathi, and Sowmya 2020). Figure 1 presents an overview of the proposed system model, which highlights the optimization parameters and the application domains. Figure 2(a)–(c) shows the system model example, with the general MPSoC design and the bridge arrangement with the processor in detail. Every processor (P) in the system is designed with in-built memory and a local bus. This work uses microblaze processors and processor local bus (PLB) interconnects in the system design. In the interest of attaining a sizeable possible design space, the proposed architecture comprises the novel execution of the MSO algorithm combined with the game model concept to facilitate the designer to achieve the best possible configuration with reduced area consumption and enhanced performance gain in a brief time.
Comprehensive Power System Stability Improvement with ROCOF Controlled SMES
Published in Electric Power Components and Systems, 2020
Hailiya Ahsan, Mairajud Din Mufti
In this paper, a simple genetically tuned ROCOF based SMES control scheme has been explored for improving transient stability in a large wind farm integrated WSCC system. The design parameters have been achieved while minimizing a mixed integral squared error as the cost function against situations of power system transients. Detailed SMES modeling and four-zone converter action is highlighted besides capturing the DC link dynamics. Realization of the said control strategy necessitates local bus estimates only. The ROCOF technique of SMES active power control shows promising aspects, by imparting sufficient damping as well as robustly curtailing the power system swing overshoots. In addition, the patchy penetration of wind power as well as different contingency situations are resiliently addressed by using the ROCOF based SMES units. Study indicates that the proposed ROCOF based SMES control is much more effective than the conventional SMES control owing its origin to the frequency error regulation. Non-linear time domain simulations (using MATLAB/Simulink) along with small signal stability modes prove the potency of the suggested schemes.
