We will be modifying our push button demo to use two buttons, and to be synchronized using clock. We will also cover how to slow the synchronized clock down to a manageable rate. This will be combined with the push button demo to see how clock synchronization can affect the sampling of an input. It…

We will be creating a push button project from scratch. The idea is that pressing a button connected to the FPGA will turn on a series of LEDs. We will then make the design synchronous by creating a slow clock out of a counter. We will also be creating a test bench file for the…

This will be the second session of the new class. If you want in, it’s not too late! Please E-Mail fpga@unallocatedspace.org to let the instructor know you want to join. We will be covering: 1. Launching ISE 2. Building example blinky light project 3. Launching Impact, Mojo Loader, and Adept for bit file uploading 4.…

This will be the first session of the new class! Very Important: Please go to http://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.html and download ISE for your operating system!!!! Unallocated Space does not have the Internet bandwidth to support downloading the 6GB install file! The class slides are here. We will be covering: Introductions What are FPGAs How are FPGAs structured…

If you are interested in joining the class, check out the new class announcement! Due to technical issues, we still need to work on getting push and pop converted over to using the SRAM. After finishing push and pop, the class will be open to questions and discussions. Please bring a breadboard and jumpers so…

We will finish integrating SRAM into our CPU. Please bring a breadboard and jumpers so that you can hook up the external memory chip. If you cannot bring those items, please contact fpga@unallocatedspace.org (or the instructor directly) to ensure enough supplies are brought with the instructor. Required Items: 1. Laptop with Xilinx ISE installed. Please…

We will be integrating our SRAM module into our custom CPU. This will require quite a bit of modification to the existing CPU code. We will also be using the simulator to make sure our design works as planned. Please bring a breadboard and jumpers so that you can hook up the external memory chip.…

Late notice 🙁 We will be finishing up our SPI SRAM interface. The only parts left are to create a test module to send test data to the actual chip, and then to work the module into our existing CPU. Please bring a breadboard and jumpers so that you can hook up the external memory…

We will finish work on our pointer instructions for the CPU. After that, we will start work on an SPI interface for SRAM. I do no expect that we will finish, but we should at least get the state machine coded up. The SPI module will not be specific to the CPU, but will eventually…

Subject: Forensics Why forensics? Often, when I talk about CTFs to people, they picture it being solely about exploiting boxes at Defcon. While exploiting is indeed a flashy part of CTFs, it is only a portion of the skills used to qualify or compete in a CTF. This month’s meeting is to inform/remind people that…
