In case of access to slower memory, the access time may be extended by wait cycles ( one wait cycle lasts one machine cycle, which is equivalent to two wait states ).
22.
Some activities act as wait states, like for example human tasks or waiting for an external service to return results . jBPM will manage and persist the state of the process instances at all times.
23.
Most hardware is based on the system clock, not the program execution speed, and the hardware access still runs through the 8-bit bus with the wait states intact, so this particular modification does not affect any peripherals.
24.
This process is called " Interleaved Direct Memory Access " ( IDMA ) by Motorola and ensures that the processor and VDG always have full access to this shared memory resource with no wait states or contention.
25.
If either one does not, wait states will be inserted until two cycles after they both do . ( The value of IRDY # and TRDY # at other times is irrelevant and they are usually deasserted .)
26.
The advantage of this scheme ( compared to other methods such as wait states or handshake-based transfer protocols ) is that the latency of credit return does not affect performance, provided that the credit limit is not encountered.
27.
The programmer or compiler tries to fetch data in time to be used and store data before more data needs the same register, but if it is not ready the processor goes into a wait state until it is.
28.
When it is not practical or economical to have all devices as fast as the CPU, the CPU must either enter a wait state, or work at a slower clock frequency temporarily, to talk to other devices in the computer.
29.
Like the 8080, the 8085 can accommodate slower memories through externally generated wait states ( pin 35, READY ), and has provisions for Direct Memory Access ( DMA ) using HOLD and HLDA signals ( pins 39 and 38 ).
30.
This is about throwing up in a foreign country . " In an interview on NPR's " World Cafe ", aired December 15, 2006, Waits stated that Tom Traubert was a " friend of a friend " who died in prison.
