clock rate |
Also found in: Encyclopedia, Wikipedia | 0.06 sec. |
clock rateFrequency of a computer's internal electronic clock. Every computer contains an electronic clock, which produces a sequence of regular electrical pulses used by the control unit to synchronize the components of the computer and regulate the fetch-execute cycle by which program instructions are processed. A fixed number of time pulses is required in order to execute each particular instruction. The speed at which a computer can process instructions therefore depends on the clock rate: increasing the clock rate will decrease the time required to complete each particular instruction. Clock rates are measured in megahertz (MHz), or millions of pulses a second. Microcomputers commonly have a clock rate of 8-100 MHz. The overall performance of a microcomputer depends on many factors in addition to the clock rate. |

Fully-functional CS301 Running at Target Clockspeed on First Tapeout; Intel designed the Pentium 4 processor with built-in throttling (a reduction in the clockspeed when the CPU encounters excessive heat). What is beyond doubt however is that by leveraging existing corporate know-how in this way, SERbrainware will increase the overall clockspeed of an organisation. |
