ASH1: Another Milestone

It’s always nice to have a meeting at AESTE. It charges you up and gives you the necessary motivation. If you want to get motivated … AESTE should be your destination where you can see ambitious people pursuing their passion.. For the next phase of my work on ash1. It’s Read more

ASH1: FPGA proven!

It has been a while since my last blog … I was busy with my exams and university issues  for about a month. So, here we come again to talk about ash1. Since I have started working on ash1, I was anxiously waiting for the day where I can write Read more

Welcome Lunch

I was being informed that my blog posts were too technical until a point that it bored the readers. I felt pity for my supervisor, because he needs to read through all my dull blog posts before publishing them. The reason that I prefer to blog technical stuff is that Read more

uCLinux: Processes in kernel

Processes can be classified as either I/O-bound or processor-bound. As the name suggests, the former is a process where much of the time is spent in waiting for relatively slow I/O operations to complete. For instance, a process taking input for a word processor will be I/O-bound as it spends most of its time Read more

LLVM: Compiling FreeRTOS with LLVM (Part 2)

Continue from my previous post, LLVM: Compiling FreeRTOS with LLVM (Part 1). Anybody who might have some basic skills in programming, creating Makefiles especially, must be laughing hysterically if they come across and read my previous post in this topic. When I google the phrase “Compiling freertos with llvm” or Read more

uCLinux: Multitasking in Linux kernel

Multitasking operating system is a software that offers interleave execution of more than one process. It is capable of executing several processes concurrently and therefore giving an illusion of parallelism in the view of user abstraction. Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. In cooperative multitasking, a process does not stop running until it is Read more

LLVM: Compiling FreeRTOS with LLVM

It is about two more weeks before my internship at Aeste ends. Yesterday, I finished my task of cleaning up LLVM floating points instructions and cache instructions. What I did was just hunt all these unwanted instructions inside AEMB target directory files and remove it without damaging the files or Read more

LLVM: Cleaning up instructions

My recent task is to clean up the instructions from LLVM code. One must wonder why do I need to clean up the instructions, well perhaps the definition of my recent task was not adequately explain here. AEMB is considered as binary compatible to the Xilink Microblaze (Wikipedia link), however Read more

QEMU: Carry and Carry Copy

AEMB is a family of highly-rated open-source embedded microprocessor core. All the programs for AEMB have to run in a simulation environment, because the core has not yet been implemented in silicone chip. Recently, one of the interns is assigned with the porting of AEMB for QEMU. With the QEMU ported Read more
