Explanation of the cycle steeling in latch based design

Dear friends

can any body explain me the cycle steeling concept in latch based design

Regards

cycle steeling

it is nothing but blocking of clock to certain parts of the circuit...

so, what's the difference between this definition and clock gating ?

sorry... replied in a hurry and got confused....

cycle stealing is using up of certain cycles of the clock in a CPU or microcontroller to perform DMA operations...

how ?

i didnt get you.... what do u want me to explain more???

cycle steeling

how to use these clock cycles to perform DMA operations ?

 

[A.Anand Srinivasan]

cycle steeling

the processor can release the bus for DMA when the device requests DMA....

Re: cycle steeling

In simple terms the present clock cycle is borrowed from the next clock cycle... due to the lack of sufficent clock period....

Dear friends

I hope my question was not clear

This particular topic i asked is regarding the static timing analysis using prime time

Re: cycle steeling

my reply was also w.r.t STA...
when ever u do timing analysis if the data is to be processed and the clock cyclez are not sufficient then in such cases required no. of clock cylces are taken frm the next state and this is is wht is known as clock stealing...

thanks for helping me in understanding the concept
