Segmentation-based Memory Protection Mechanism on Intel Atom Microarchitecture: Coding Optimizations

The Intel Atom processor is explicitly designed to achieve efficient performance and low-power operation, adopting special in-order microarchitecture. The development of highly-optimized software applications requires the use of specific coding techniques. The purpose of this paper is to emphasize some aspects of the segmented memory protection mechanism implemented in the Intel Atom microarchitecture. A developer can use this information to create a higher-performing solution.
