Node:clobber, Next:clock, Previous:CLM, Up:= C =

clobber vt.

To overwrite, usually unintentionally: "I walked off the end

of the array and clobbered the stack." Compare mung, scribble,

trash, and smash the stack.

=

clock

1. n 1. [techspeak] The master oscillator that steps a CPU or

other digital circuit through its paces. This has nothing to do

with the time of day, although the software counter that keeps

track of the latter may be derived from the former. 2. vt. To run

a CPU or other digital circuit at a particular rate. "If you

clock it at 100MHz, it gets warm.". See overclock. 3. vt. To force a digital circuit

from one state to the next by applying a single clock pulse. "The

data must be stable 10ns before you clock the latch."

Node:clocks, Next:clone, Previous:clock, Up:= C

=

clocks n.

Processor logic cycles, so called because each generally

corresponds to one clock pulse in the processor's timing. The

relative execution times of instructions on a machine are usually

discussed in clocks rather than absolute fractions of a second;

one good reason for this is that clock speeds for various models

of the machine may increase as technology improves, and it is

usually the relative times one is interested in when discussing

the instruction set. Compare cycle,

jiffy.
