The kind of LEGO blocks we had while growing up were simple: 2×4, 2×2, 1×8. Anything unusual was rare and precious.Continue reading
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.
