A 60‐GHz on‐chip slot‐array antenna in integrated‐passive‐device technology for antenna‐in‐package applications

A new millimeter‐wave antenna structure on a low‐cost, production platform integrated passive device technology is presented. The antenna consists of a 2‐by‐1 array of slot antennas at 60 GHz. An in‐house developed on‐chip antenna measurement setup was used to characterize the fabricated antenna. The measurement results show an antenna gain of more than 5 dBi with a return loss of 18 dB at 60 GHz. The better‐than‐10‐dB impedance bandwidth of the antenna covers the 60‐GHz unlicensed band from 57 to 64 GHz. The 3‐dB beamwidths of the antenna are 105° and 76° at E‐plane and H‐plane at 60 GHz, respectively. The size of the die of the antenna is 2 mm × 4.5 mm. © 2013 Wiley Periodicals, Inc.

MoNoC: A monitored network on chip with path adaptation mechanism

Complex systems on chip containing dozens of processing resources with critical communication requirements usually rely on the use of networks on chip (NoCs) as communication infrastructure. NoCs provide significant advantages over simpler infrastructures such as shared busses or point to point communication, including higher scalability, more efficient energy management, higher bandwidth and lower average latency. Applications running on NoCs with more than 10% of bandwidth usage attest that the most significant portion of message latencies refers to buffered packets waiting to enter the NoC, whereas the latency portion that depends on the packet traversing the NoC is sometimes negligible. This work presents an adaptive routing architecture, named Monitored NoC (MoNoC), which is based on a traffic monitoring mechanism and the exchange of high priority control packets. This method enables to adapt paths by choosing less congested routes. Practical experiments show that the proposed path adaptation is a fast process, enabling to transmit packets with smaller latencies, up to 9 times smaller, by using non-congested NoC regions.

片上网络业务量的自相似性分析及模型研究

进行片上网络的架构、映射、流控与服务质量(Quality of Service,QoS)等研究时,迫切需要一个准确的业务量模型用于延时分析与测试验证,以保证设计的性能。而现有的基于马尔科夫模型和回归模型的短程相关模型无法准确地描述业务量的突发性和分形特性,不适用于基于流水的通信信号处理片上系统(System on Chip,SoC)芯片。为了解决这个问题,通过理论与实验相结合的方法,研究了网络拓扑、任务流图、映射对业务量自相似性的影响,根据通信系统的信号处理特点建立了多处理器片上系统(Multi-core Processing System on Chip,MPSoC)数据关联模型,利用典型DSP系统进行建模实验,用实测的业务量Hurst参数拟合数据关联模型参数与Hurst参数的经验函数关系式,建立了用MPSoC数据关联模型预测和估计业务量Hurst参数的方法。实验表明,采用该业务量模型估计的Hurst参数与其真实值误差较小,能较准确地描述业务量的自相似性。
