DirectFB (Direct Frame Buffer) is a graphics library that is widely used in embedded systems, especially home market. More and more applications or libraries choose DirectFB as backend, such as Cairo,…

Great leaps in human knowledge are linked to advancements in tools. For software engineers the debugger is a cornerstone tool to create reliable products. We engage in a running battle fighting both the…

Here at ARM, a colleague recently wanted to port Linux to a prototype of a new high-performance Cortex-A9 based platform.  To develop and debug this port, he needed to be able to set breakpoints, view…

This blog covers the use of two powerful debugging techniques — stack frames and instruction trace — to debug random or timing-related bugs on ARM processor-based targets.Timing-related and random bugs…

In this blog you will find information about semihosting, an implementation of the C library that uses a JTAG debugger to interface the world. Semihosting is very useful for board bring-up, as it works…

Debugging and optimizing software is always a demanding job.  As today's  systems become more complex the task of providing a suitable debug and  trace solution becomes increasingly challenging - yet it…

This post goes into the juicy bits of what memory access ordering actually means and how this is handled in the Arm architecture.

This article is the first of a series on Arm fundamentals that will introduce various topics to help you get more familiar with the Arm architecture.

Page colouring is sometimes used as an optimization but as a result of the cache architecture some ARMv6 processors actually require the allocator use page colouring. This article will explain why the…

When writing code for Neon, you may find that sometimes, the data in your registers are not quite in the correct format for your algorithm. We explore this in further detail here.
