Code Wrangling at its Best
Regarding the difference between simulation and emulation:
Not limited to computers I use this distinction:
– A simulation mimics the outward appearance
– An emulation mimics the cause/process.
If you want to convince people that watching television gives you
stomach-aches, you can simulate this by holding your chest/abdomen and
moan.
So which is better? The answer to this question, like so many things in computer science is “it depends”.
Creating the Tiny-P CPU In this post, we will finally write some code. I promise! We’ll be using Python here as one of the most popular languages these days according to the Tiobe index, narrowly beating out C. So, in the interest of reaching as many people as possible I settled on Python for this
Programming the Tiny-P Programmers are often confused by the terms machine language and assembly language. Many developers consider these two terms interchangeable. But in fact, they mean very different things. If you go back to the Tiny-P Opcode table presented in part-3 of this series, you can see how the various machine code values are
Tooling Hardware and software developers are tool makers by trade. Just like a machinist, software developers often need to develop their own tools for the job at hand. Sometimes these tools are simple scripts to automate a boring, or complicated task, or perhaps, a tool to fill a yet unfilled niche. Whatever the reason, tool
Last issue we built a simple assembler for our TIny-P processor emulator. In this installment, we will build a loader. But what is a loader? Loaders are small programs that load other programs into system memory and prepare them for execution. Most loaders are part of an Operating System however, in the embedded world, there
Today’s Project NOTICE: Today’s Code will only work under Python 3.10 and later. In this episode, we will build a new system using a processor with Von Neumann Architecture. We will also be splitting our system into various files and classes to organize our system better. The Memory will no longer be part of the
Adding a Crude Console Last time, we left off with a working computer system using the Tiny-T processor. I told you that we would add a very crude terminal to the system this time. The terminal I’ll present today is barely a terminal. It won’t have any special functions, text scrolling, or any other features
Tooling for the Tiny-T When we completed the console, last installment, I had said I was unsure what I would cover next. I’m really wanting to begin implementing our audio device, but I felt that adding a GUI for the Tiny-T system was a target much more achievable in the limited time I had. However,
