You might have realized from my previous post that I often bring a lot of emotion to programming. I code best and come up with the best designs when I’m happy and on a roll, but that’s also when I miss the most blatant bugs. When I’m down and struggling, I take longer to synthesize information, but because I force myself to inch my way toward progress, I sometimes discover things I had never known and would never have known Read more…
As mentioned in the previous post, I’ve decided to work on μClinux kernel porting as my project in AESTE. I will briefly introduce it in this post. μClinux (Micro-Controller Linux) is a linux kernel targeted for embedded devices without memory management unit. μClinux was first implemented in DragonBall integrated microprocessor, Motorola MC68328 back in 1998, and it has now ported to many embedded systems in various areas. Examples of these devices include Apple iPod, Sigma Designs EM8500 based DVD players, IntelliCom Read more…
Some people observe that life is an uphill journey and all that matters is The Climb. I believe no such simple analogy for my career here at Aeste. You may remember that my task is to port the AEMB to QEMU and that I have successfully replicated an existing architecture as a first step. I was under no illusion that what was to come after that would not be much more difficult—but to say that I was completely prepared would Read more…
Week 2 Day 1: So, the project decided. Its porting LLVM compiler into AEMB. Time to get the code. Should get svn version or release version? First, lets try the svn version. The error said: svn: Malformed XML: not well-formed (invalid token) Eh? What now? This must not be the only problem on this earth. Google it, found this. Week 2 Day 2: Spent the whole day try to hand-tweak each time the problem occurred. Still stuck. Week 2 Day Read more…
Hello and good day, As part of task as an intern at Aeste, I was asked by my supervisor to regularly write blog about the task and the experience here. So, this is it. Ahmad Shaiful Amiruddin bin Taher, born in Marang, Terengganu. Final year student, BE(Hons) candidate from Faculty of Engineering, Multimedia University Cyberjaya Campus. Graduation expected, 2012. Insha Allah. Well, how did I end up here at a start-up company when every colleagues of mine all chasing those Read more…
Here I am, on the third day of my internship at AESTE, typing away my thoughts and recollections from the past half-week. In the background, the whirring of the air-conditioning and fan accompanies Jason Mraz and James Morrison as they prescribe that everything will be fine (if it’s broken code then fix it)… I arrived at AESTE on Wednesday feeling anxious (read: a little scared) because I was clear of my abilities. I wasn’t gonna try to fool anyone into Read more…
During my first week in my company, I was very excited and eager to choose my very own project. However I am very new to the work that I am going to do. I have only very basic experience in C programming, minimal knowledge in assembly language and almost zero Verilog/VHDL. I doubt my ability to program something from scratch. Luckily I am allowed to modify an existing open source code. I am interested in working on making an instruction Read more…
This post presents the sixth and the last phase of porting FreeRTOS for AEMB processor. In the previous post, both interrupt and interrupt handling were implemented to serve the mechanism of the preemptive kernel. Although, things seemed fine and set, yet the kernel failed to work when FreeRTOS tasks were created. This problem by far was one of the most complex problems that I faced during my progress in the project. It was hard to tell what was going wrong!! Read more…
This post represents the fifth phase of porting FreeRTOS for AEMB processor. The main concern of this phase is to get the FreeRTOS configured to demonstrate the Preemptive Multitasking. By far this phase deals with the following: Setting up the timer to generate the RTOS Tick Handling the RTOS Tick In the previous post, cooperative multitasking was intoduced and successfully demonstrated. However in cooperative multitasking, the interrupt and the interrupt handling had not yet been implemented. As a result, there Read more…
I’m a final year student from Multimedia University (MMU), currently pursuing Bachelor of Engineering (Honours) in Electronics. As for my first post in AESTE’s blog, I’m sharing my experiences on job application to AESTE, and the work progress thus far. The job application to AESTE involved two stages. The first stage is answering screening questions in Google Doc, which covered areas in Processor Architecture, Software Programming, FPGA/ASIC Design, Computer Networking and Web Development. Following this was the phone interview by my supervisor, Read more…
