What Is the Difference Between a Hard Real-Time System and a Soft Real-Time System
Early in my embedded career I made the mistake of treating “real-time” as a single, fuzzy buzzword —…
How Does an Embedded System Handle Analog Signals
The real world is analog. Temperature, pressure, light, sound, vibration — none of it arrives as clean digital…
What Is the Role of a Signal Conditioning Circuit in an Embedded System
I once spent an entire week chasing what looked like a firmware bug in a load-cell weighing system,…
How Does an Embedded System Handle Sensor Data
Getting a number off a sensor is the easy part. What I’ve learned over years of building IoT…
How Does an Embedded System Handle Communication with Other Devices or Systems
No embedded device I’ve built in the last decade has been an island. Even the simplest sensor node…
What Is the Purpose of a Real-Time Clock (RTC) in an Embedded System
I once shipped a batch of data loggers that used the microcontroller’s internal software counter to keep track…
How Is Power Consumption Managed in Battery-Powered Embedded Systems
The single hardest constraint I’ve ever designed against wasn’t timing or memory — it was a customer requirement…
How Does Caching Affect Performance in Embedded Systems
I remember benchmarking an image processing routine on a Cortex-A-based embedded Linux board and getting wildly inconsistent timing…
What Are the Different Types of Memory Used in Embedded Systems
One of the first design reviews I ever sat in on as a junior engineer involved a senior…
How Is Multitasking Achieved in an Embedded System
When I first started working with microcontrollers, I assumed “multitasking” meant something like what my laptop does —…
