Once we’ve built a computer, the next step is to develop an assembly language and then an assembler that can assemble our programs. In my previous column, we introduced the concept of the big-endian ...

A programming language that is one step away from machine language. Each assembly language statement is translated into a machine instruction by the assembler. Programmers must be well versed in the ...

Originally computer programs were written in machine code – sequences of binary ones and zeros – and reprogramming was a laborious process involving much rewiring and changes of switches. Assembly ...

When my grandfather died six months ago, my sister said it felt as if we had lost a family archive. We knew he was an electrical engineer who began his career at the dawn of digital computing. We knew ...

In the days before computers usually used off-the-shelf CPU chips, people who needed a CPU often used something called “bitslice.” The idea was to have a building block chip that needed some ...

Assembly is the lowest level human-readable programming language. Today, it is used for precise control over the CPU and memory on the bare metal hardware of a computer. Learn the basics Assembly with ...

What if you could strip away the layers of abstraction that operating systems impose and interact directly with your computer’s hardware? Imagine crafting a program where every instruction is executed ...

We’ve come to the point where we need to define an assembly language for our 4-Bit HRRG Computer, but first we need to consider certain concepts. These days, we are used to programming our computers ...

We all probably know that for ultimate control and maximum performance, you need assembly language. No matter how good your compiler is, you’ll almost always be able to do better by using your human ...
