The Dining Philosophers Problem

The dining philosophers problem is a classic problem in the realm of computer science. If you’ve had any formal CS education you’ve more than likely seen the problem when learning about concurrent programming.

Today we will take a look at the problem and look at an example of how we can solve it.

Let’s Write a Simple Disassembler for the Intel 8080 Microprocessor

Typically my weekends are spent hiking with my camera, but this past weekend I was knocked down by a pretty nasty cold. As a result, I found myself toying around with various programming projects I’ve had laying around. Here for a while, I’ve been curious how emulators work, so I took this opportunity to start venturing down that rabbit hole. During this excursion, I decided to start my foray into emulators by writing one for the game Space Invaders, which ran on an Intel 8080 microprocessor. It seemed only natural to get started by writing a disassembler for the 8080 to get things started.

What I came up with is a pretty simple (albeit long) bit of C code to disassemble binary code compiled for the Intel 8080. So, without further ado, let’s jump on in and see how I did it!
