Embedded Application design help needed

This is my first Embedded related project and needs
to be done on fast track so i need your help.
I have some knowledge of linux,written few modules
but not much as far as programming in linux is
Tech Back ground of the Proj.
I have an SBC(PCI bus) and A.) Analog Input
card B.) Analog O/p card c.) Digital input Card d.)
Digital O/p Card.
I want to know how to design my application , i mean
i don't know anything about embedded linux. In other
words can somebosy tell me what should be there in
1.) My Analog Input card has onboard FIFO and it does
conversions from analog to digital at some rate which
is lets say very fast like 2000 samples/ second.(PCI
based Analog i/p card), I want to scan the card evry
10 msec and store the data , i should give higest
priority to this task.
2.) The samples mentioned above are taken from some
sensors which are mounted over a rail and they move at
To and Fro at a speed of 200mm/sec, i want to give
this task 2nd highest priority. These sensors are
moved TO and Fro using AC induction motor i also have
to control the motor (direction and speed).
3.) I need to store the captured samples in the memory
and do some computation.
4.) After the computation is done i need to run a PID
loop(some loop). This loop should be executed once
5.) At the same time i also need to pass on this
averaged value to a PC running windows on in via
LAN.This task can be of lower priority.
6.)If required i need to run some diagonistic's from
Lets assume that drivers for Analog I/p , Analog O/p ,
Digital i/p and Digital o/p cards are avialable.
Can somebody help me to get started with it. may be i
can refine the Design here on the list.
