How a Clever 1960s Memory Trick Changed Computing

LaurieWired explains the history and mechanics of virtual memory, paging, and translation lookaside buffers, starting with the 1960s Atlas supercomputer.

Ever wondered how your computer can run multiple programs at once? Join me as we explore the historical innovations of Britian's Atlas supercomputer, enabling efficient multitasking and memory management that modern computing relies on. We'll cover various computer engineering and operating system topics, such as Virtual Memory, Memory Management Units, Translation Lookaside Buffers, as well as Spatial and Temporal locality! --- Follow LaurieWired on Social Media: ►linktr.ee/lauriewired --- Timestamps: 00:00 Intro 01:07 Physical Memory Addressing 05:12 Virtual Memory Addressing 10:53 Translation Lookaside Buffer 17:42 Closing Thoughts --- Resources on Memory Paging: x86 Paging: Vol 3A Part 1 Chapter 4, Paging: intel.com/content/dam/www/public/us/en/documents/manuals/64-… Vol 3C Part 3 Chapter 28, VMX Support for Address Translation: intel.com/content/dam/www/public/us/en/documents/manuals/64-… Arm Paging: AArch64 Memory Management Guide: developer.arm.com/documentation/101811/latest RISC-V Paging: The RISC-V Instruction Set Manual: Volume II, Sections 10.3 through 10.6: riscv.org/technical/specifications/ --- Atlas Emulator for Modern PCs: icsa.inf.ed.ac.uk/research/groups/hase/models/atlas/ --- Intro Music by Analog Summer: youtube.com/@AnalogSummer-FL
