Building Linux Kernel for Desktops
Linux Development has made an amazing process in last decade. Different Linux Distributions come with specific tools which greatly ease down the build process for Linux Kernel.
Here is a good introduction to these build tools and build procedure for different Linux Distributions:
Hello Android
Finally I could get Android Early SDK up and running on my Fedora Core-7 Machine.
The process was quite simple. However I had to struggle for a few days, because Fedora install the gnu version of Java and Android requires Java from Sun.
Here are the steps I had to follow:
(1) Install the eclipse IDE (if you do not have it already) with following command:
$> yum install eclipse-jdt eclipse-jdt-sdk (to be done as super user).
(2) now install the Android SDK and ADT plug-in for Eclipse...
Configuration Management: Why Developers are Avert to
A few reasons why developers have aversion towards "Software Configuration Management Systems"
(1) They do not understand the importance of configuration management. - It is a common and logical reason. But, it is also a very dangerous sign for any organization. If their developers do not understand the importance of configuration management; then it is highly likely that developers even do not understand the other fundamentals of software development. The situation becomes worst...
Embedded Space & Software Development Practices
Embedded Programmers (at least the ones I know) are mostly at liberty to ignore the basic software development best practices, thanks to the simplicity of embedded applications. But, as the embedded processors are becoming more and more powerful, this situation might change soon. In coming years the embedded software applications are bound to become more complex (some embedded segments have already seen this change). Embedded programmers need to realize this inevitable change and start...
Designing Embedded System with FPGA - 1
With the introduction of soft processors and related tools (like EDK from Xilinx), implementation of basic embedded system in FPGA is made easy. This requires very little or almost no knowledge of VHDL programming. Actually that’s how I started. If user is interested in taking full advantage of FPGA and its parallel processing power, then yes, detail understanding of soft processor, its peripheral bus and VHDL programming is required.
I will start with...
Thumb Rules for Effective Meetings
Meetings are unavoidable at any work place. At most occasions, meetings can be frustrating. We all face meeting-nightmares in our professional life.
I worked on a project, where none of the team-members were ever interested in any kind of group discussion or formal communication. At early stages of the project, no one wanted to be a part of decision making process. During middle-stages of the project, no one wanted to share any status updates or discuss any critical issues. And finally when...
Debugging DSP code.
I am fascinated with neural network processing and have been playing with them since the 80's.
I am a frequent contributor to the Numenta forum. Numenta is the current project of Jeff Hawins, the guy that gave us the Palm Pilot. They are working with the HTM model. This is a system based on studies of the functions of the cortical column and has some very interesting properties: It processes sequential data streams and has very effective one shot learning. The data is arranged in Sparse...

Software Prototyping
In my recent blog entry on the product development process (way down, near the end of the entry), I wrote the following:
"I continue these sorts of tests, building more and more complexity, until I am satisfied that my circuit is basically functional. Then, using the test code that I have created as a model, I begin to write the real software for my product. As my software grows, to complete the full functionality of my design, I sometime find it useful to drop back to my 'test software'...
Lightweight hardware abstraction
Some lessons are tougher than others to master. You would think that hard fought battles would be easier to remember, but sometimes it just does not work that way. Recently, I was asked to pick-up a project that had been managed by another employee. The project was yet another cost reduction project. The hardware group was tasked with updating a currently shipping product, to reduce the existing failure rate, while at the same time to remove cost from the...
“Smarter” cars, unintended acceleration – and unintended consequences
In this article, I consider some recent press reports relating to embedded software in the automotive sector.
In The Times newspaper (London, 2015-10-16) the imminent arrival of Tesla cars that “use autopilot technology to park themselves and change lane without intervention from the driver” was noted.
By most definitions, the Tesla design incorporates what is sometimes called “Artificial Intelligence” (AI).Others might label it a “Smart” (or at least “Smarter”)...

Simple Automated Log Processing
Text log data offers a wealth of information from an embedded system. At least during prototyping and development phases, most systems have some kind of serial log output, or use semihosting methods to log to a serial output channel in a debugger. Then you can capture the logs to a file.
The problem is that they tend to accumulate large volumes of data. Logs can be many thousands of lines long, especially when you run long duration tests. Finding information and evaluating trends in the...
Scorchers, Part 2: Unknown Bugs and Popcorn
This is a short article about diminishing returns in the context of software releases.
Those of you who have been working professionally on software or firmware have probably faced this dilemma before. The scrum masters of the world will probably harp on terms like the Definition of Done and the Minimum Viable Product. Blah blah blah. In simple terms, how do you know when your product is ready to release? This is both an easy and a difficult question to answer.
What makes...
