An operating system (OS) is an optional part of an embedded device’s system software stack, meaning that not all embedded systems have one. OSs can be used on any processor (Instruction Set ...

This paper presents an instruction set simulator of an 8-bit, MCS-51 compatible CPU core, and shows how to use it in embedded software development process; Method to control and debug CPU using ...

If instruction sets didn't matter, processors would be cheaper and designers would have more options. That's why one startup's efforts are so intriguing. Every microprocessor is different, in part ...

When developing software for small microcontrollers, it is common to use assembly language in the final product. But there is still much value in prototyping the software and its algortihms in C. Here ...

Cortus released the APS23 and APS25 32-bit processor IP cores, based on v2 of the company’s instruction set. The new instruction set aims to reduce the size of a system’s instruction memory, usually ...

The design of embedded systems realised in System-on-Chip (SoC) form is increasingly turning to the use of configurable and extensible processors. Such designs start at a high level of abstraction, ...

To some, an operating system is a burden or waste of resources, like those working on embedded systems and other low-power applications. To others it’s necessary, abstracting away hardware so that ...
