  2. Bus snooping - Wikipedia

    en.wikipedia.org/wiki/Bus_snooping

    If the cache is dirty and shared and there is a request on the bus for that memory, a dirty snooping element will supply the data to the requester. At that point either the requester can take on responsibility for the data (marking the data as dirty), or memory can grab a copy (the memory is said to have "snarfed" the data) and the two elements ...

  3. List of Linux distributions that run from RAM - Wikipedia

    en.wikipedia.org/wiki/List_of_Linux...

    Tiny Core Linux is an example of Linux distribution that run from RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.

  4. Unique set size - Wikipedia

    en.wikipedia.org/wiki/Unique_set_size

    In computing, unique set size (USS) is the portion of main memory occupied by a process which is guaranteed to be private to that process. The unshared memory of a process is reported as USS. [1] This concept is used for software running under the Linux operating system. [2]

    en.wikipedia.org/wiki/Memory_controller

    A memory controller, also known as memory chip controller (MCC) or a memory controller unit (MCU), is a digital circuit that manages the flow of data going to and from a computer's main memory. [1] [2] When a memory controller is integrated into another chip, such as an integral part of a microprocessor, it is usually called an integrated ...

  8. Booting process of Linux - Wikipedia

    en.wikipedia.org/wiki/Booting_process_of_Linux

    The Linux kernel handles all operating system processes, such as memory management, task scheduling, I/O, interprocess communication, and overall system control. This is loaded in two stages – in the first stage, the kernel (as a compressed image file) is loaded into memory and decompressed, and a few fundamental functions are set up such as ...

  9. RTLinux - Wikipedia

    en.wikipedia.org/wiki/RTLinux

    RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.
