  2. Multithreading (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Multithreading_(computer...

    A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.

  3. Thread (computing) - Wikipedia

    en.wikipedia.org/wiki/Thread_(computing)

    A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1]

  4. Simultaneous multithreading - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_multithreading

    The term multithreading is ambiguous, because not only can multiple threads be executed simultaneously on one CPU core, but also multiple tasks (with different page tables, different task state segments, different protection rings, different I/O permissions, etc.). Although running on the same core, they are completely separated from each other.

  5. Single-core - Wikipedia

    en.wikipedia.org/wiki/Single-core

    A single-core processor is a microprocessor with a single CPU on its die. [1] It performs the fetch-decode-execute cycle one at a time, as it only runs on one thread.A computer using a single core CPU is generally slower than a multi-core system.

  6. Hyper-threading - Wikipedia

    en.wikipedia.org/wiki/Hyper-threading

    Architecturally, a processor with Hyper-Threading Technology consists of two logical processors per core, each of which has its own processor architectural state. Each logical processor can be individually halted, interrupted or directed to execute a specified thread, independently from the other logical processor sharing the same physical core ...

  7. Multi-core processor - Wikipedia

    en.wikipedia.org/wiki/Multi-core_processor

    Diagram of a generic dual-core processor with CPU-local level-1 caches and a shared, on-die level-2 cache An Intel Core 2 Duo E6750 dual-core processor An AMD Athlon X2 6400+ dual-core processor A multi-core processor ( MCP ) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs ...

  8. Single instruction, multiple threads - Wikipedia

    en.wikipedia.org/wiki/Single_instruction...

    For instance, to handle an IF-ELSE block where various threads of a processor execute different paths, all threads must actually process both paths (as all threads of a processor always execute in lock-step), but masking is used to disable and enable the various threads as appropriate. Masking is avoided when control flow is coherent for the ...

  9. Task parallelism - Wikipedia

    en.wikipedia.org/wiki/Task_parallelism

    The exploitation of thread-level parallelism has also begun to make inroads into the desktop market with the advent of multi-core microprocessors. This has occurred because, for various reasons, it has become increasingly impractical to increase either the clock speed or instructions per clock of a single core.
