In this post we will create an Arithmetic & Logic Unit (ALU) using logic gates. The ALU is one of the main component of the CPU. It is used in the Execution stage of the FDE cycle to perform all…

In our previous blog posts we have looked at a few logic gates circuits used inside a CPU to perform binary additions (Half adders and full adders) and to retain a bit of information using a D-Type flip-flop circuit (Data…

In our previous blog post, “Binary Additions using Logic Gates”, we investigated how logic gates can be used together to create a circuit used in the ALU (Arithmetic & Logic Unit of the CPU) to add two binary numbers together.…

In our previous blog post “from transistors to processors” we found out that the CPU consists of logic gates, which are made using transistors. In this blog post we are looking at how these logic gates can be combined to…

Vacuum Tubes and Transistors: Many consider the transistor to be one of the most important inventions of all time. Though the precursors of the transistor were invented in 1907 (at the time they were not transistors yet, they were vacuum…
