This week, I continued to work on the timing signal generation for CCD sensor. It is also my first time to actually write a real Verilog code that describes the circuit I drew. Initially, I started to rely on Icarus Verilog Simulator, which turns out that the output waveform is the ideal waveform that I was looking for. After working and tested for several timing signals, I decided to test it on the Xilinx ISE tools to check on my work. Read more
This week, I spent a while studying more about stringstream and boostsystem in order to be able to work on separating the upload and download feature into independent WResources to ensure that it can be called by other projects when required i.e. comprise of individual entrypoints. I made a step by step check-list of how I would want to proceed with the separation as all of them which had already been under the same WApplication. Retrieving the access_token was the priority Read more

This week is pretty interesting, as I was working on the timing signals for the CCD. In order to perform demosaicing, my supervisor advised me to understand on the operation of the CCD. The CCD Phase Signal The CCD sensor will only operate and controlled by the timing signals that are supplied to the pins. I found this link to be useful in understanding the fundamental of CCD, such as the phase shifting of CCD output. Besides, CCD would have Read more
It works! It works! It finally works!! I can say my “Upload/ Download” finally works after weeks of struggling with it. That was a joyous moment for me. This would have my last week fighting to get the feature working. After a lot of trial and error with various syntax and protocols, I have succeeded in showing Dropbox Upload/Download feature functioning for sample .txt files. As I have mentioned in the last week’s blog, I had been stuck with Error 404, which Read more
For this week, I’ve worked on several different things, mostly to complete the linking between schematic, compiler and processor simulator. To communicate among the components, I have used emit() in Wt which implement the signal and slot system. Jsignal and Jslot The signal and slot system allows user to send up to 6 arguments. In official Wt documentation, there is little elaboration on how to perform the Wt.emit function. In any web application, it is important to send information among Read more
This is my sixth week of intern in AESTE. I started the week with discussing with Maisha on how should I get started on using Wt. She taught me some of the basic stuff of Wt and with the help of Peter, they set up a simple Wt Application template for me to write my HOTP library on the template and also so that my work will not conflict with theirs. I am really fortunate because all my current colleague Read more
The struggle is real. As mentioned before, considering the fact that Dropbox is only created to support Javascript, Python, Ruby, HTTP etc. So there is faint hope of these being anything similar to what I am working on- witty, a library of C++. So their documentations are quite irrelevant to my case. Since the basic concept is the same, I have been using the HTTP documentation for reference. Initially in the week, I was struggling to grasp the idea of which part Read more
Creating an IO object After nearly giving up and getting some hints from Dr. Shawn, I finally achieved my small task. As I am working on a virtual processor in Javascript, I am required to enhance the LW and SW instructions to be able to handle IO instructions on port-mapped addresses. There are a set of predefined addresses which are used to store the information of the IO. So, it is important that the IO addresses are being handled correctly. Read more
This week I was assigned to draw the schematic for the demosaicing algorithm. The algorithm is separated into two parts, which is bilinear interpolation in the boundary of image, and PPG interpolation for the rest of image pixels. The Overview of Demosaicing Schematic The hardware implementation of the demosaicing requires the storing of pixels information in buffers (RAM), processing, and finally output in RGB form. As I was finding the way to store the buffer, I found that there is Read more
