The ever decreasing scale in microelectronics
Ever since the beginning of the microelectronics era there has been an eternal quest to reduce the characteristic features on the devices: some devices are now in qualification states on the sub 40nm gate oxide range for an scheduled commercial release towards the end of the year, and there are a lot of efforts in the sub 30nm range. But Moore’s Law, as this continuous drive to reduce sizes has come to be called, applies not only to the dimensions on the silicon. It spreads down through the whole microelectronic supply chain, into pcb packages, system integration and final devices.

Please do not get confused by the title. This resource book is not talking about EDA software for Electronics Engineering. We collected these open project resources for those programmers who are only familiar with PC computer, instead of embedded systems. Some of the programmers are experts on the x86 computers, but they do not know how to light a LED at all. Because they have not experience in development for the embedded systems. After all, this resource book is trying to demonstrate those projects which are using traditional high level programming languages on standard PCs and desktop operation systems to manipulate some hardware devices. We hope the software experts can easily migrate their experience on embedded system involved in a real working project.

Today, the boundaries between the general purpose PCs, the servers and the embedded systems are more blurred. These computers are sharing same platfroms, same periperals. For example, an x86/Mac PC can be used as a server, an x86/PowerPC CPU can be used in an embedded system like portable navigation device (PND). On the other way, the popular embedded processor StrongARM was a powerful desktop PC processor for the DEC workstation, and the embedded systems often also act servers, like NAS (Network Attached Storage). As same as the hardware suppliers, the OS suppliers port their products into the desktop PCs, servers and embedded systems.

I am Qprox QUANTUM consultant and Design Partner Microchip Technology, but now I have decided!
In the next project I'll use a Cypress Semiconductor product! Why?
Because Cypress is performant... as the rest of its employees!

A lot of users have the experience of virtual machines. These VMs are quite useful for developers who have to working on multiple OS platforms. There are many VMs running on embedded microcontrollers, too. These embedded VMs are dedicated for specific purpose. A lot of embedded applications leverage them to reduce system complexity, memory usage, and depoly the custom design. It sounds incorrect, since running VM requires extra resource of embedded microcontroller, and demands extra programming effort, either. However embedded VM indeed can help developers to achieve those goals.

Electronics Engineering requires a lot of software. Here is an overview for it.

Embedded OS will cover most of the open source and commercial operation systems and software components for embedded system.
