wait state

[′wāt ‚stāt]
(computer science)
The state of a computer program in which it cannot use the central processing unit normally because the unit is waiting to complete an input/output operation.

wait state

(architecture)
A delay of one or more clock cycles added to a processor's instruction execution time to allow it to communicate with slow external devices. The number and duration of wait states may be pre-configured or they may be controlled dynamically via certain control lines.

wait state

The time spent waiting for an operation to take place. Wait states are often idle computer cycles, because a computer's CPU is much faster than main memory. Wait states are introduced between the time the CPU requests data from the RAM (an address is placed on the address bus) until the content has been delivered to the CPU. See address bus.

In addition, Liberating Tech takes advantage of the 25 nanosecond performance of the nvSRAM to eliminate wait states for the processor, making it highly efficient.
The increased bandwidth allows memory operations to be performed in fewer clock cycles, reducing the number of wait states between instructions and increasing overall system performance.
System parallelism is accomplished via the 6x5 Smart Speed crossbar switch that nearly eliminates wait states and enables the processor to drive equivalent performance to processors with clock speeds up to 3 GHz, but without the power consumption penalty that goes with higher operating frequencies.
Ideal for small office or business customers who prefer a pre-packaged personal computer solution with the latest technologies, the Dell Dimension XPS P90 and XPS P60 systems include an ISA (Industry Standard Architecture) bus with fast PCI technology, along with Intel's 90MHz and 60MHz Pentium processors respectively, which execute faster memory transfers and reduce wait states.
