  2. Central processing unit - Wikipedia

    en.wikipedia.org/wiki/Central_processing_unit

    A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.

  3. Coremark - Wikipedia

    en.wikipedia.org/wiki/Coremark

    CoreMark is a benchmark that measures the performance of central processing units (CPU) used in embedded systems.It was developed in 2009 [1] by Shay Gal-On at EEMBC and is intended to become an industry standard, replacing the Dhrystone benchmark. [2]

  4. Processor (computing) - Wikipedia

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

    The Synergistic Processing Element or Unit (SPE or SPU) is a component in the Cell microprocessor. Processors based on different circuit technology have been developed. One example is quantum processors , which use quantum physics to enable algorithms that are impossible on classical computers (those using traditional circuitry).

  5. Direct memory access - Wikipedia

    en.wikipedia.org/wiki/Direct_memory_access

    Direct memory access (DMA) is a feature of computer systems that allows certain hardware subsystems to access main system memory independently of the central processing unit (CPU). [ 1 ] Without DMA, when the CPU is using programmed input/output , it is typically fully occupied for the entire duration of the read or write operation, and is thus ...

  6. Minimal instruction set computer - Wikipedia

    en.wikipedia.org/wiki/Minimal_instruction_set...

    Minimal instruction set computer (MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.

  7. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

  8. Multithreading (computer architecture) - Wikipedia

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

    This allowed the concept of throughput computing to re-emerge from the more specialized field of transaction processing. Even though it is very difficult to further speed up a single thread or single program, most computer systems are actually multitasking among multiple threads or programs.

  9. Control unit - Wikipedia

    en.wikipedia.org/wiki/Control_unit

    The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
