Especialização em Sistemas Embarcados

12.21.2013 · Posted in Eng. Computação, Eng. Eletrônica

A evolução contínua e o aumento da complexidade dos dispositivos mecânicos, elétricos e eletrônicos têm exigido soluções de controle cada vez mais elaboradas, robustas, escaláveis e eficientes, a tal ponto que os antigos circuitos de controle analógicos e digitais, baseados em componentes discretos, tornaram-se obsoletos e ineficazes. O curso tem por objetivo o desenvolvimento de ...

How FPGAs work

06.19.2013 · Posted in Eng. Computação, Eng. Eletrônica

“Today, pretty much everyone has a CPU, a DSP and a GPU, buried somewhere in their PC, phone, car, etc. Most don”t know or care that they bought any of these, but they did.” Leia o artigo em: http://www.yosefk.com/blog/how-fpgas-work-and-why-youll-buy-one.html ...

The Trajectory of Television

06.14.2013 · Posted in Art. Diversos, Eng. Eletrônica

“Though it”s a relatively recent invention, television is a pillar of Western—and even global—culture. Even if you”re that one guy who makes it a point to mention that you don”t watch or even own a television, your life has inevitably been shaped by the small screen to some degree. Popular culture has its moments of being swept ...

Bit Level Manipulation

04.08.2013 · Posted in Eng. Computação, Eng. Eletrônica

“Bit level manipulation allows us to write more efficient code due to the fact that CPU”s are really good at handling bits. In fact that”s all they really do. Even if you”ve never played around with bit manipulation it”s likely that your compiler has modified your code to use bit manipulation.” Leia mais em: http://maxburstein.com/blog/bit-level-manipulation/ ...

Happy birthday, Transistor

12.17.2012 · Posted in Eng. Eletrônica

By Tony Smith: The transistor, the ubiquitous building block of all electronic circuits, will be 65 years old on Sunday. The device is jointly credited to William Shockley (1910-1989), John Bardeen (1908-1991) and Walter Brattain (1902-1987), and it was Bardeen and Brattain who operated the first working point-contact transistor during an experiment conducted on 16 December ...

Are Microcontrollers Obsolete?

11.15.2012 · Posted in Eng. Computação, Eng. Eletrônica

I’ve once again been questioning whether what I am doing (designing a home automation controller based on a 16-bit microcontroller) is really a good idea. A month and a half ago I posted an article about microcontrollers versus a system on chip design. Now, if you can believe it, I am wondering about the same topic ...

Passatempo para quem gosta de eletrônica: construir um FPGA utilizando apenas componentes discretos, da linha 7400.  A célula do FPAG contém apenas 12 componentes discretos. Ler o artigo em: http://blog.notdot.net/2012/10/Build-your-own-FPGA ...

How your phone knows where it is

10.17.2012 · Posted in Eng. Computação

“Assisted GPS is used by millions of smartphone users every day to get driving directions, find places, and find themselves. As it turns out, the good old GPS satellite system, by itself, works very slowly and often not at all when you”re indoors or walking beneath tall buildings. That”s why the GPS software in your ...
