ECDSA Driver (cont.)

I continued writing the ECDSA driver this week and managed to complete it, including testing it on the simulator. My understanding of the concept of the functionalities of the ECDSA driver was obscure earlier and my colleague who worked on this has already left AESTE when I started implementing this Read more

SPI down, Uart on the way.

This week I’ve finished the second version of SPI. I basically adjusted the formatting of the code  to be more professional, easier to read and interpret and better commented. My guide is the code for AEMB, it’s formatting, nomenclature and comments. I’ve come across a bug in SPI. Apparantely the Read more

Pipeline implementation (Final Stage)

Here come the final week of my internship. After I have done my code checking and debugging for Load and Store instruction implemented earlier, I started to work on my main task of the week that is to implement IMM instruction in pipelining. This task actually wasn’t heavy but was a Read more

PCB Design and the FreeRouting Autorouter

Work on designing the PCB layout continues in earnest. We encounter a few software issues relating to the hardware of the task, which prompt some worried thoughts. As always, here’s a look back at the previous week. Click here to skip to the conclusion. Pin Assignments During design it became Read more

SOC with SHA1 and GPIO

This week we have managed to get an SOC that connects AEMB to SHA1 accelerator and a GPIO. Having only one device at each bus of the AEMB doesn’t require much effort in terms of SOC. The software that we used for testing contained our driver for SHA1. Our demo Read more

Issues with Multi-Block Writing

It turns out that issue of connection timeout, random protocol data is caused by the fact I did not call the write function after TCP and Ethernet layer processes. The write function is then called in the Ethernet layer (ETH97J60.c). The function that is modified is MACGetArray(). After this modification, Read more

ECDSA Driver

This week was really a busy week and it passed so fast that I didn’t even realize that today is Friday again! I have spent a lot of my time fixing the bugs in the SHA1 driver when it was tested on the Simulator. Later, I started to test the Read more

Pizza Lunch

My interns decided to order pizza for lunch at the office, yesterday. They managed to convince a pizza place from Bangsar to deliver to Cheras. Kudos!

GPIO custom bus completed

During my 10th week at Aeste, I continued my unfinished business from the 9th week: bit banging the gpio to implement a custom 8 bits wide bus. I spent most of my time this week debugging the gpio driver for the custom bus. My code was ready at the beginning Read more
