  2. Real-time clock - Wikipedia

    en.wikipedia.org/wiki/Real-time_clock

    Counting timers used in modern computers provide similar features at lower precision, and may trace their requirements to this type of clock. (e.g. in the PDP-8, the mains-based clock, model DK8EA, came first, and was later followed by a crystal-based clock, DK8EC.) A software-based clock must be set each time its computer is turned on.

  3. Cycles per instruction - Wikipedia

    en.wikipedia.org/wiki/Cycles_per_instruction

    In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. [1] It is the multiplicative inverse of instructions per cycle.

  4. MIPS architecture - Wikipedia

    en.wikipedia.org/wiki/MIPS_architecture

    MIPS I branch instructions compare the contents of a GPR (rs) against zero or another GPR (rt) as signed integers and branch if the specified condition is true. Control is transferred to the address computed by shifting the 16-bit offset left by two bits, sign-extending the 18-bit result, and adding the 32-bit sign-extended result to the sum of ...

    Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.

  6. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    C = A+B needs four instructions. 3-operand, allowing better reuse of data: [11] CISC — It becomes either a single instruction: add a,b,c. C = A+B needs one instruction. CISC — Or, on machines limited to two memory operands per instruction, move a,reg1; add reg1,b,c; C = A+B needs two instructions.

  7. Quartz clock - Wikipedia

    en.wikipedia.org/wiki/Quartz_clock

    Standard-quality 32 768 Hz resonators of this type are warranted to have a long-term accuracy of about six parts per million (0.0006%) at 31 °C (87.8 °F): that is, a typical quartz clock or wristwatch will gain or lose 15 seconds per 30 days (within a normal temperature range of 5 to 35 °C or 41 to 95 °F) or less than a half second clock ...

  8. Clockmaker - Wikipedia

    en.wikipedia.org/wiki/Clockmaker

    By the 19th century, clock parts were beginning to be made in small factories, but the skilled work of designing, assembling, and adjusting the clock was still done by clockmaking shops. By the 20th century, interchangeable parts and standardized designs allowed the entire clock to be assembled in factories, and clockmakers specialized in ...

  9. Real Time (art series) - Wikipedia

    en.wikipedia.org/wiki/Real_Time_(art_series)

    Maarten Baas's Schiphol Clock. Real Time is an art installation series by Dutch designer Maarten Baas. It consists of works in which people manually create and erase the hands on a clock each minute. Portions of the time depiction are completed using CGI after the motions of the painter are filmed separately and repeated to complete the 24 hours.
