Design of an Embedded System

[avssunil]

Hello All,
Can an Embedded System be designed without a clock????Is it possible??

 

[budhy]

Without clock? No, can't!
Without Cristal? Yes

 

[ivar4ever]

AFAIK no.

 

[dipal_z]

No, i don't think its possible because all sequence of operations is based on clock.

If your embedded system is only some combinational gates ( a very trivial embedded system ) answer is yes.

For any real embedded system, it must contain at least any processing element which must use a clock to activate all the sequential FF's.

like budhy said, without crystal, yes you can have something made if you ensure that a clock like signal is still generated and provided... and that it is steady...
however its really not possible to have an embedded system without a clock...

infact i would say that someting that runs without a clock is not really an embedded system...

regards,

no. it is not possible without clock.

thanks.

Embedded system always run in MCU or CPU. MCU or CPU need clock to execute instruction. Such as AT80S51 needs 12 clock to execute one instruction.

An embedded system without a clock that pulses = A human without a heart that beats

 

[fireplus]

Who that can be ?
the colck is the heart of all the logic operation that can embedded system do .

No, it is impossible to design an embedded system without a clock because it syncronize the operation in ur system

 

[jayavardhan]

sorry without clock it is not possible.

 

[yousafzai]

Not without clock...

 

[rickleicn]

impossible,if no clock,the ff will not work,as a result,the cpu will not work,so your code will not be fetched from memory and executed.

 

[dragonight_x]

No way :!: , the clock is one of the essentials in embedded systems

 

[vaibhav.k]

No
without clock u cant do anything in Embedded.Cause clock is heart of Controller.

Without a clock embedded system can not be designed. Because clock is main part which controls the various functionalities, scheduling and timers. You can generate a clock signal by a circuitry without a crystal aso but that is also a clock signal. Synchronization is the main thing in embedded system without it system will crash.
