In this article we will go through the steps required to setup Linux on the PandaBoard using files supplied from Linaro and also the further steps required to setup Linux for use with Development Studio…

The modern web is built primarily from three technologies: HTML, CSS and JavaScript. It is JavaScript that drives the interactive web; slow JavaScript means slow web pages. So today, a huge amount of effort…

In my first blog, we examined gave the historical context of the instruction set battles of ARM and x86, covering the RISC-CISC Wars in the PrePC Era and the PC Era. This blog covers Round 3, the PostPC…

This two-part blog gives a historical perspective on the ARM vs. 80x86 instruction set competition for three eras: PrePC (late 1970s/early 1980s), PC (mid 1980s to mid 2000s), and PostPC (late 2000s onward…

The 2010 ARM Technology Conference (Techcon) is taking place in Santa Clara next week. A large number of companies will be presenting their solutions to support development and optimization of products…

Wow it's that time again; our 4th release of Ubuntu on ARM is upon us. In the past we have provided a Freescale iMX51 image, a Marvell Dove image and a TI OMAP 3 image for Beagle Boards. This cycle…

In the last article, I explained how to modify SWP code to make use of compiler intrinsics.  Using intrinsics hides the underlying detail needed to use the load and store exclusive instructions (LDREX…

Before ARMv6, the main synchronisation mechanism was the SWP instruction. SWP has two aspects, in a uniprocessor system it allows the read and write operations not to be interrupted between them.   In…
