A homebrew 3D graphics coprocessor.
An old project of mine may return from the dead. A few years ago, I started an ambitious project to build a 3D graphics processor using an FPGA. The goal was to create a simple version of the GPU you…
Maybe 3D Graphics Thingy isn’t dead after all. One of my goals for the creation of Tiny CPU was to get more comfortable with programmable logic design, and custom circuit board development, and I’ve certainly done that. Once Tiny CPU…
OK, it’s time to admit defeat. 3D Graphics Thingy is not going to happen. It’s been six months since I worked on it. Heck, I even let my web hosting account expire due to neglect. So what happened? I ran…
I think I’m making life more difficult than it needs to be, trying to get this DDR2 SDRAM interface to work. It’s not that the logical interface is so complicated, really… you set your row and column addresses, do a…
Finally, some small progress on the memory interface. After banging my head every which way against the Xilinx tools, and reading everything I could find on the subject, I came across Leo Silvestri’s page on modifying the Xilinx MIG memory…
I think I’m about ready to crush this Xilinx starter kit under my boot, and use the pulverized component dust to scrub my toilet. That’s not quite fair, though, as my frustration isn’t really with the hardware, but with the…
