C Arrays, behind the scene !!

An Array in C is a collection of similar types of data elements. It is a built-in data type and is widely used by developers. Here, we will cover the array declarations, the memory layout, array decay, and multi-dimensional arrays.

Function Pointers - Everything you need to know!

In this post, we explore what a function pointer is, what it really means for the machine, how to define it, and how to use it.

What is an Embedded System?

Embedded systems typically have a “sense the environment”, “evaluate” and “do something to the environment” loop. The intention is to sense the environment and then influence it to get the desired effect.

Hardware Development Using FPGA

Hardware development flow using the open-source toolchain for synthesis, place-n-route, and programming of ice40 FPGA. We use Blinky as an example to guide the discussion.

Redifining Global in C

This post explores how redefinition of a symbol may be possible when using the C language.

CPUs, Pantries, and Caches

What is common between Chefs and CPUs in terms of how they strive for efficiency? 🥸

0.1 is not 0.1. Yups!

Computers can’t store 0.1 accurately. It is stored as 0.1000000015! In this post we explore and take a look at what is really going on.

C: Constant Is Not Constant

const does not mean that the variable is constant. In this post, we explore the true meaning of the const qualifier and its implications.

FPGAs for the rest of us

FPGAs can be programmed to become digital circuit of choice. The code becomes the hardware! We explore the mechanics behind how the FPGA might be able to implement circuits.

4 things to look for to master any Processor!

Any time I have to work with a new CPU architecture, I look for the details on the four area discussed below.
