hello ladies and gentlemen;
i've a more complex homework this time.
i'm writing my homework down:
"The design of central process unit of a photocopier is wanted."
The inputs of cpu are;
i've three weeks to complete this. i will share my solving progress with you if i advance anything
i've a more complex homework this time.
i'm writing my homework down:
"The design of central process unit of a photocopier is wanted."
The inputs of cpu are;
- copy number in 3 bits,
- "start copying" input,
- the input of a sensor
(the function of the sensor is to detect stucked papers -- but this function is not important in the design)
- 3 bit data which shows number of remaining sheets (R)
- motor control (M),
- Print output (B)
- to start copying, copy number is entered in 3 bits. then "start" input applies a pulse.
- remaining copy number = entered copy number
- after one pulse diagram shown in figure is intercepted, remaining number decreases 1
- if R isn't equal to zero, process will be repeated
- during copy process, if "stucked paper" input=0, then process will be stopped (M=0, B=0).
i've three weeks to complete this. i will share my solving progress with you if i advance anything
