Pulse width modulator

by Juha Lumme | December 2013 | Networking & Telephony Open Source

In this article by Juha Lumme, the author of BeagleBone Home Automation, we can drive our GPIOs to high or low state, and if we have an LED attached in our circuit, it will either light up or not. We can control the brightness by adjusting the resistance in the circuit, but this is a static way to do it, and once our circuit is complete, we can't change the resistor easily.

So, how can the LEDs on your wrist watch, mobile phone and remote control then fade in and out so perfectly? This is where pulse modulation comes in.

Fast Array Operations with NumPy

by Gabriele Lanaro | December 2013 | Open Source

NumPy is the de facto standard for scientific computing in Python. It extends Python with a flexible multidimensional array that allows fast mathematical calculations.

NumPy works as a framework that allows coding complex operations using a concise syntax. The multidimensional array (numpy.ndarray) is internally based on C arrays: in this way the developer can easily interface NumPy with existing C and FORTRAN code. NumPy constitutes a bridge between Python and the legacy code written using those languages.

In this article, by Gabriele Lanaro, author of Python High Performance Programming, we will learn how to create and access NumPy arrays.

In the last few years a number of packages were developed to further increase the speed of NumPy. We will explore one of these packages, numexpr, that optimizes array expressions and takes advantage of multi-core architectures.

Hello OpenCL

by Koushik Bhattacharyya Ravishankar Somasundaram | December 2013 | Open Source

In this article by Ravishekhar Banger and Koushik Bhattacharyya, authors of the book OpenCL Programming by Example, we will learn the basic concepts of OpenCL. Parallel Computing has been extensively researched over the past few decades and had been the key research interest at many universities. Parallel Computing uses multiple processors or computers working together on a common algorithm or task. Due to the constraints in the available memory, performance of a single computing unit, and also the need to complete a task quickly, various parallel computing frameworks have been defined. All computers are parallel these days, even your handheld mobiles are multicore platforms and each of these parallel computers uses a parallel computing framework of their choice. Let's define Parallel Computing.
