What is a serial-to-parallel shift register?

A serial-to-parallel shift register (or SIPO: Serial In Parallel Out) lets you take a sequence of signals on one output, and split them up into several separate outputs. For example, if you don’t have enough GPIO pins on your Raspberry Pi, Arduino, or other computer/microcontroller, you can use a shift register to add more. In …

Creating a $99 parallel computing machine is just as hard as it sounds

Ten months ago, the chipmaker Adapteva unveiled a bold quest—to create a Raspberry Pi-sized computer that can perform the same types of tasks typically reserved for supercomputers. And… they wanted to sell it for only $99. A successful Kickstarter project raised nearly $900,000 for the so-called “Parallella,” and the company got to work with a …
