Finally from the review, I found that the real time computations using equations will be slow in '51. So I did the offline calculations in Matlab. And I have the desired output values. But my problem is that I have to give that output switching pattern at different time intervals. Whether this could be done in 8051, help me please.
For better understanding i am giving the problem briefly below...
My problem is that from 2-input(signals) values I have to find the switching pulses(9-different pulses). I have done the offline calculations, sample result is shown below.

Time------------------------------p1 p2 p3 p4........p9

If i am storing the P1....P9 values in EPROM, then how can I run the microcontroller to fetch the EPROM values at variable time intervals. Is it possible? and also can I operate the microcontroller for such minute time intervals? as a Timer.

Please give suggestions for this problem
