His design has an 8-bit data bus but a 4-bit ALU, and an impressive 2-stage pipeline and RISC instruction set which sets it apart from the computers most of us had when 74-series logic was a much ...

To learn how to start using Logisim, let's look at how to set up one of the most basic logic circuits: an AND gate. Figure 2. You easily can add logic gates to your circuit to model computations. If ...

It relies on what they term "seesaw" logic gates, which we've diagrammed below. The central feature of these gates is a stretch of DNA that can base-pair with many different molecules, allowing ...
