It has been a while since I wrote the last post about this project. In the meantime, I was able to dedicate all my free time to work on the implementation. As I was making really good progress, the calculator started taking shape. My excitement grew and I just could not stop the work to write about it....continue reading "A Calculator – Completed!"
For as long as I remember, I had played with LEGOs. Those simple blocks would transform into complex objects whose final shape only existed in the supple thoughts of creative imagination. The kind of LEGO blocks we had while growing up were simple: 2x4, 2x2, 1x8. Anything unusual was rare and precious....continue reading "A Calculator (4): The Framework"
A-Z80 is a conceptual implementation of the venerable Zilog Z80 processor targeted to synthesize and run on a modern FPGA device. It differs from the existing (mostly Verilog) Z80 implementations in that it is designed from the ground up through the schematics and low-level gates.
This article is about using an Altera FPGA board to generate images on a VGA monitor.
