[Podcast] An Inventory of x86-64 CPU Registers

https://blog.yossarian.net/2020/11/30... This technical overview examines the complex architecture of x86-64 CPU registers, highlighting how their numbers and functions have evolved over decades. The author establishes specific criteria for counting these components, including sub-registers, legacy registers, and non-addressable Model Specific Registers (MSRs). The text categorizes these into groups such as general-purpose, special-purpose, segment, and SIMD/floating-point registers, noting how many are nested within one another. Beyond standard operations, the discussion covers debug, control, and bounds registers that facilitate system management and software testing. By filtering through extensive documentation to identify architectural MSRs, the author concludes that a modern processor contains approximately 557 distinct registers. This analysis serves as a detailed map for understanding the diverse internal storage locations that drive modern computing. #computerscience #computer #cpu
