The increasing industrial demand for low data-rate and low power networking protocols for IoT communications from past several years led to the development of ZigBee technology. As a result of advancement in VLSI technologies, development of more power efficient, accurate, and small digital ZigBee transmitter design has become achievable but yet challenging. This paper presents digital design and...
High Efficiency Video Coding (HEVC) and VP9 are the latest state-of-the-art high-efficiency video coding standards. Both standards aim to decrease the bit-rate while improving the compression efficiency. HEVC/H.265 video standard was collaboratively developed by ITU-T and ISO/IEC with up to 50% bit-rate reduction as compared to its predecessor H.264/AVC. On the other hand, VP9 is an open source video...
Commonly, navigation uses global positioning system/network (GPS) signals to determine location. In addition, GPS data can be collected over time to determine the path taken. In spite of the ubiquity of GPS signals on the earth’s surface, there are certain locations where GPS signals are not available, such as inside buildings or tunnels. Therefore, to determine accurate positioning in areas where...
Dynamic Random Access Memory (DRAM) has been prevalent over the past few decades as main memory component. The demand of higher memory capacity is increasing continuously, while scaling of DRAM is reaching its boundaries. As we scale DRAM to smaller feature size, difficulties in fabrication, leakage power, and energy consumption become significant. Therefore, memory technologies, which have better...
Emergence of big data sources at a rapid rate extends the necessity of old data organization due to the large volume, velocity, variety, value, and veracity of this data. Performing timely analysis on huge datasets is the central promise of big data analytics. The frameworks used to compose analytics jobs into a Directed Acyclic Graphs of small tasks, and then aggregate the intermediate results from...
The rapid development in wireless networking has been witnessed in past several years, which aimed on high speed and long range applications. The increasing demand for low data and low power networking led to the development of ZigBee technology. This technology was developed for Wireless Personal Area Networks (WPAN), directed at control and military applications, where low cost, low data rate, and...
