Real World Multicore Embedded Systems: Chapter 15. Bare-Metal Systems

Some embedded systems require so much performance that they cannot tolerate the overhead imposed by an operating system. Such systems can be built with little to no operating system services, and are often referred to as “bare-metal” systems. Because most programming techniques rely on system services, bare-metal programming requires a different way of implementing code on a multicore platform. This chapter describes where bare-metal systems are used, those aspects that differentiate them from more standard systems, and how they can be designed and programmed.
