Challenges in the Design of Integrated Systems for IoT

Abstract

The Internet of Things is moving fast to be the Internet of Everything. This brings several challenges in several areas of Computing Systems, as in Embedded Systems, Computer Architectures, Fault Tolerance and Integrated Circuits and Systems. One common point is the power optimisation, as the demanding energy is increasing year by year. Optimisation must be done in all levels of design abstraction, system, computer architecture till the physical design. Another issue is reliability and fault tolerance as systems at ground level can be affected by radiations reaching the ground. Also, as several devices in IoT are related to sensitive applications, security is also an important issue in different design levels, including the physical one. The talk will present an overview of all these issues, proposing also some solutions.

In-materioneuromimetic devices: dynamics, information processing and pattern recognition

“…[16][17][18][19][20][21] 2.1. The case of the BZ reaction The BZ reaction is a catalyzed oxidative bromination of malonic acid in aqueous acidic solution (1): Various metal ions or metal-complexes, such as either cerium ions or ferroin [i.e. tris-(1,10-phenanthroline)-iron(II)] or tris(2,2′-bipyridyl)dichloro-ruthenium(II) (Ru(bpy) 3 2+ ) can serve as catalyst.…”

“…The story of information processing is a story of great success. Todays' microprocessors are integrated circuits of unprecedented complexity and MOSFET transistors are considered as the most widely produced component in the history of mankind, with a total number of fabricated devices easily exceeding several sextillions (10 21 ) 1) The contemporary microprocessor contains approximately 3.95 × 10 9 transistors. 2) In a human, there are an estimated 10-20 billion neurons in the cerebral cortex and 55-70 billion neurons in the cerebellum.…”

Desafios para o Brasil construir sua Sociedade 5.0

“…Cabe também observar que Computação e Eletrônica são áreas que cada vez mais estão se fusionando. Uma constatação importante é que o número de dispositivos computacionais/eletrônicos conectados na Internet das Coisas tem crescido em uma velocidade acelerada [3], sendo uma das principais razões de um crescimento impressionante do número de transístores produzidos anualmente no mundo. Na figura 1, podemos observar que em 2014 foram produzidos 250 quintilhões de transistores no mundo e que em 2017, apenas 3 anos depois, a produção aumentou Não haverá como atender a demanda de uma futura Sociedade 5.0, a não ser que haja uma mudança significativa nos métodos de projeto de sistemas computacionais, uma mudança que tenha como foco a otimização do consumo de energia.…”
