X-CUBE-CRYPTOLIB (CMOX) and the STM32's CRC unit

This write-up is about the STM32 cryptographic firmware library X-CUBE-CRYPTOLIB, also known as the Cortex-M Optimized Crypto Stack (CMOX). It is a cryptographic library developed by STMicroelectronics (ST) for their series of STM32 processors, which are based on the ARM Cortex-M family.

Hardware features vary across different STM32 processors. Because CRC checksums are widely used in embedded systems, most (if not all) STM32 processors feature a hardware CRC unit that is supposed to accelerate CRC computations.

Introduction

Interestingly, on the page "Getting started with the Cryptographic Library", ST claims:

During the past days, this great article by Sam Pruden has been making the rounds around the gamedev community. While the article provides an in-depth analysis, its a bit easy to miss the point and exert the wrong conclusions from it. As such, and in many cases, users unfamiliar with Godot internals have used it points such as following:

• Godot C# support is inefficient
• Godot API and binding system is designed around GDScript
• Godot is not production ready

In this brief article, I will shed a bit more light about how the Godot binding system works and some detail on the Godot

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

raylib: 6 years of fun

raylib has been in development for more than six years now, it has been an adventure! I decided to resume how it was my personal experience working in this free and open source project for such a long time. Just note that the following article explains raylib from a personal point of view, independently of the technical aspects and focusing on the personal adventure; for technical details on raylib evolution, just check raylib history and raylib changelog.

Summer 2012 was ending, I had been working hard on my brand new startup emegeme for about 9 months, developing videogames. I was trying to find my blue-ocean, so, I developed and published two games for Windows Phone platform using the ama
