  2. Burn-in - Wikipedia

    en.wikipedia.org/wiki/Burn-in

    Burn-in is the process by which components of a system are exercised before being placed in service (and often, before the system being completely assembled from those components). This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established.

  3. Halt and Catch Fire (computing) - Wikipedia

    The 6800's behavior when encountering HCF was known to Motorola by 1976. When the 6800 encounters the HCF instruction, the processor never finds the end of it, endlessly incrementing its program counter until the CPU is reset. [13] Hence, the address bus effectively becomes a counter, allowing the operation of all address lines to be quickly ...

    Classic Complex Instruction Set Computer (CISC) ISAs optimized by providing a larger set of more complex CPU instructions. Generally speaking, however, complex instructions inflate the number of clock cycles per instruction C l o c k C y c l e s I n s t r u c t i o n {\displaystyle \mathrm {\tfrac {ClockCycles}{Instruction}} } because they must ...

    R0 is used as the DMA address pointer. The starting address of the DMA data would be put in R0 and then pulling the appropriate read or write pin on the CPU low. The CPU responded to the DMA request by incrementing the value in R0, so that the next request automatically stored in the next location in memory.

  6. Programmable ROM - Wikipedia

    Burning a fuse bit during programming causes the bit to be read as "0" by "blowing" the fuses, which is an irreversible process. Some devices can be "reprogrammed" if the new data replaces "1"s with "0"s. Some CPU instruction sets (e.g. 6502) took advantage of this by defining a break (BRK) instruction with the operation code of '00'. In cases ...

    In computing, an eFuse (electronic fuse) is a microscopic fuse put into a computer chip.This technology was invented by IBM in 2004 [1] to allow for the dynamic real-time reprogramming of chips.

    time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.

  9. Benchmark (computing) - Wikipedia

    A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
