  2. ESP32 - Wikipedia

    en.wikipedia.org/wiki/ESP32

    ESP32 was a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...

  3. ESP8266 - Wikipedia

    en.wikipedia.org/wiki/ESP8266

    SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...

  4. CPU modes - Wikipedia

    en.wikipedia.org/wiki/CPU_modes

    Several computer systems introduced in the 1960s, such as the IBM System/360, DEC PDP-6/PDP-10, the GE-600/Honeywell 6000 series, and the Burroughs B5000 series and B6500 series, support two CPU modes; a mode that grants full privileges to code running in that mode, and a mode that prevents direct access to input/output devices and some other hardware facilities to code running in that mode.

  5. Memory bandwidth - Wikipedia

    en.wikipedia.org/wiki/Memory_bandwidth

    Using the same 1 million byte copy example, the hardware bandwidth on computer systems with a write allocate cache policy would include an additional 1 million bytes of traffic because the hardware reads the target array from memory into cache before performing the stores. This gives a total of 3 million bytes per second actually transferred by ...

  6. Stress testing (computing) - Wikipedia

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

    A stress test (sometimes called a torture test) of hardware is a form of deliberately intense and thorough testing used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.

  7. Reliability, availability and serviceability - Wikipedia

    en.wikipedia.org/wiki/Reliability,_availability...

    Computer clustering capability with failover capability, for complete redundancy of hardware and software. Dynamic software updating to avoid the need to reboot the system for a kernel software update, for example Ksplice under Linux. Independent management processor for serviceability: remote monitoring, alerting and control.

  8. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:

  9. Embedded system - Wikipedia

    en.wikipedia.org/wiki/Embedded_system

    An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
