"Network-on-Chip Architectures: A Holistic Design Exploration" by Chrysostomos Nicopoulos Publisher: Springer | ISBN: 9048130301 | 2009 | PDF | 223 pages | 9 Mb The continuing reduction of feature sizes into the nanoscale regime has led to dramatic increases in transistor densities. Integration at these levels has highlighted the criticality of the on-chip interconnects. Network-on-Chip (NoC) architectures are viewed as a possible solution to burgeoning global wiring delays in many-core chips, and have recently crystallized into a significant research domain. On-chip networks instill a new flavor to communication research due to their inherently resource-constrained nature. Despite the lightweight character demanded of the NoC components, modern designs require ultra-low communication latencies in order to cope with inflating data bandwidths. The work presented in Network-on-Chip Architectures addresses these issues through a comprehensive exploration of the design space. The design aspects of the NoC are viewed through a penta-faceted prism encompassing five major issues: (1) performance, (2) silicon area consumption, (3) power/energy efficiency, (4) reliability, and (5) variability. These five aspects serve as the fundamental design drivers and critical evaluation metrics in the quest for efficient NoC implementations. The research exploration employs a two-pronged approach: (a) MICRO-architectural innovations within the major NoC components, and (b) MACRO-architectural choices aiming to seamlessly merge the interconnection backbone with the remaining system modules. These two research threads and the aforementioned five key metrics mount a holistic and in-depth attack on most issues surrounding the design of NoCs in multi-core architectures.

目录LoRa简介硬件设备源码分析`Sender`两种调制方式 LoRa简介 详细的LoRaWAN协议解析在这里 本文主要介绍LoRa在Arduino上的实现过程,从而学习LoRa协议的实现。 硬件设备 包括传统的GFSK调制技术以及LoRa(远程)扩频技术 这里说一下啥叫LoRa扩频技术 扩频通信的基本思想:根据香农公式**C = W * log2(1 + S / N)**,为了提高信号的传输速率C,可以增加带宽W或者提高信噪比S/N,即当传输速率一定时,带宽与信噪比可以互换。扩频通信就是用带宽换信噪比。 LoRa目前主要在ISM频段运行,包括433、868、915MHz等。LoRa的优势在
