RISC and Superscalar Architectures

• The Linux kernel's RCU (Read-Copy-Update): A direct evolution of the read-write locks described in 1994.
• NUMA-aware allocation: What 1994 called "cache affinity" is now "node affinity" in EPYC and Xeon CPUs.
• Memory ordering macros: Every kernel programmer today uses smp_mb(), smp_wmb(), exactly as codified in those 1994 Alpha documents.

Practical Hardware Examples: The text uses real-world examples from the era, such as the Intel Pentium, MIPS R4000, and Motorola 68040, to bridge the gap between computer architecture and OS design. Key Topics Covered Internet Archive (archive

Deep Caching Insights: It offers one of the most detailed explanations of cache lines, associativity, and the difference between virtual and physical caches.
