Hello RTLinux community,
I am sure that many of you have computed the amount of
time necessary to accomplish various tasks in real-time operations.
I am trying to factor in memory access. I have from a
personal conversation that the typical memory bus runs at 100 MHz.
Thus
I am assuming that one can access a32-bit word in 10
nano-second (i.e. access time about 1 byte per 2.5 nano-second).
Thus, to read/write
from/to an array of 1MB in RAM should take 2.5
milli-seconds.
Does this figure stack up with your experience or am I way off
of the mark?
Cheers,
Jeff Ridgway
