Week 0100

The last week wasn’t that productive, although I still learned a lot, mainly theory, about different hashing techniques. Did you know what are “nothing up my sleeve numbers” or Chaitin-Kolmogorov random numbers? Anyway, after looking more closely at the MD5 algorithm and consultation with my boss, we decided in the middle of the week that I should rather focus on SHA1 algorithm for now. The reason is simple, the later seems to be more implementation friendly and require less memory Read more

Week 0011

Miracle! The design we’ve been working on in the previous week works perfectly! Honestly speaking the main merit goes to my colleagues, as their part was more crucial (mine was just a wishbone master sending some 8-bit combinations through switches), but still, I feel relieved. Funny, I’m pretty sure I wouldn’t believe if someone had told me few years ago that the sight of blinking LEDs would make me happy. There is a short video and some more detailed explanation Read more

RS 232 rx

This week i finished up writing the code for the receiver uart. My design includes a transmission register, a state register,  a status register and a few counters. This was the first time, I was using a finite state machine in my design.  My design would wait for a start bit and receive the bits with respect to a count that is a parameter.  When it is time to sample the stop bit, the design would indicate if there was Read more

My 2nd week at AESTE

They say the first week is always the hardest. At the start of my second week, I was supposed to get the computer to read and write into an SD card by programming the PIC18F8722. After being on the receiving end of the massive scolding last week, I was being very fearful of getting it again and I guess the fear really hampered my thoughts and I wasted one day looking completely at the wrong direction in trying to find Read more

New Kid on the ‘Blog’

This is going to be my first weekly blog post at Aeste! I just joined this company as intern. As for the first week of my internship, Shawn asked me to study Git and do some C programming tutorials just to make sure that my understanding of the C language is decent enough to study the Linux Kernel which will be one of the main tasks during my internship here. Git is a version control tool to keep track of Read more

Our Summer Interns

There were over two hundred applicants for our summer internship places this year. There was a stringent screening process and in the end, we have nine interns for the summer. We have a really good mix of summer interns this year. Our nine interns are working on various aspects of our new product, from chip-design through to web-application development. In terms of alma maters, we have five of whom are studying at some of the top universities in the world Read more

Week 5: SPI done!

So it has been 2 weeks since the last time I’ve blogged and a lot have happened since then. Today we just finished the design and testing of the SPI peripheral device. That includes an SPI Master and slave that are wishbone compatible and a dummy master to test those two devices. We have tested the design using simulation and by implementing it on 2 FPGA boards connected together through SPI signals. Don’t get too excited reading the above statement Read more

SPI Finishing

On my fifth week here, I finished up the SPI that was compatible with the Wishbone bus. I was able to have it working for the four modes of the SCLK. I had to make many changes to the design because I did not have the right idea of the SPI’s functionality to begin with. My colleague Mostafa and my boss Shawn took some time to explain to me several issues regarding my MISO and and how similar the four Read more

First week at AESTE

My first week at AESTE, I was introduced to something that I have never used before which was the new operating system of Ubuntu. Being a complete tyro at it, I was a little puzzled at how this operating system works. I was required to learn about the GIT software which was very useful in the management of source files. Thankfully, a link to the tutorial was given and it greatly helped me in familiarising myself with the new OS. Read more

Shooting Troubles #2

This lab was really annoying in terms of things that didn’t want to work When trying to export hardware for SDK in PlanAhead error shows [Common 17-49] Internal Data Exception: xps application failed SDK requires gmake, we can solve it by simple linking: cd /usr/bin sudo ln -s make gmake After adding Board Support Package in SDK, it is automatically build. While compiling, error shows /bin/sh: 1: arm-xilinx-eabi-gcc: not found Reinstalling the package like described on this page http://www.wiki.xilinx.com/Install+Xilinx+Tools helps Read more
