The steps for building an embedded system (development board) for a particular application are described bellow.

The real world, where we live day by day, is the realm of analogue signals. Read this overview about ADC (Analog to Digital Converter) and DAC (Digital to Analog Converter)

RTOS stands for Real Time Operating System. An embedded system is a combination of hardware and software integration, accomplished for a specific function.

Are you afraid that your circuit could be damaged by an overvoltage? Include the hardware protection listed in the following paragraphs to protect your hardware!

1.General Aspects
PWM (Pulse Width Modulation) – represents a periodic square wave signal with a variable duty cycle. Duty Cycle (D) – represents a fraction between the time when the system is on active state (“logic state 1”) λ, and the period of the system T.

Cache is a small and very fast type of memory. Cache, as a concept, means a type of buffer between the processor and the main memory.

Linux is becoming a very popular operating system, especially for embedded domain. From 1991 it was continuously developed and now it is one of the most popular operating system. A lot of hardware platforms (microcontrollers) are using embedded Linux, some of them being ARM, PowerPC, Intel.
