An optical limited scan antenna system is considered for applications such as spot coverage of a small portion of the earth from a satellite. The optimum criterion relating aperture efficiency, number of control elements, and angular coverage is revisited briefly. The optical scheme advocated utilizes a bootlace aperture lens, a generalized Luneberg lens focused to the near field, and a small array of active elements. The operation of the system is described first in terms of geometrical optics and elementary diffraction principles. The subarray viewpoint is then developed using simplified diffraction concepts. These results form the basis of a design procedure for the synthesis of high performance limited scan systems. An accurate solution necessary for the analysis of small antennas is developed using a modal decomposition and the wave equation. Numerical computations for a case of practical interest verify the expectation of near optimum performance. 相似文献

集成电路已经发展到了SoC(System on Chip)时代,在系统设计领域就需要有相应的EDA工具的支持。CoCentric就是由Synopsys公司推出的SoC系统设计的EDA工具。CoCentric系统设计流程是由综合和验证这两个并行的流程组成的。综合着重实现从系统设计到最后硬件语言描述实现的过程;而验证则通过系统仿真来保证在综合过程中,系统的功能保持一致。文末还详细介绍了一个用CoCentric设计的SoC信息安全芯片的系统设计,并讨论了如何在这一系统中进行软硬件的划分。 相似文献

The voltage/frequency island (VFI) design paradigm is a practical architecture for energy-efficient networks-on-chip (NoC)
systems. In VFI-based NoC systems, each island can be operated with different voltage and clock frequency and thus it is important
to carefully partition processing elements (PEs) into islands based on their workloads and communications. In this paper,
we propose an energy-efficient design scheme that optimizes energy consumption and hardware costs in VFI-based NoC systems.
Since on-chip networks take up a substantial portion of system power budget in NoC-based systems, the proposed scheme uses
communication-aware VFI partitioning and tile mapping/routing algorithms to minimize the inter-VFI communications. Experimental
results show that the proposed design technique can reduce communication energy consumption by 32–51% over existing techniques
and total energy consumption by 3–14%. 相似文献

The design of a mobile or portable radio communications system requires the consideration of a number of unique engineering factors which do not necessarily apply to the design of a fixed, or point-to-point system. The design procedure is a combination of theoretical and empirical methods, which when taken with measured data, produce a system design meeting the required specifications. This paper will treat that portion of the system design pertaining to radio frequency propagation and system coverage. It stresses a realistic measurement program which will provide coverage data in support of the system design. 相似文献
