Best solution for pci target and backend interface |
|
|
I use in my project a pci target ( it a free core from Lattice). I
must to control some devices (a few motors and other things...) and I
choise to do this through pci. One of the signals that control the
motor are start/stop, run/brake, dir,..... I must to send command for
this motor through pci. After pci target module I interfaced a ram
block where in location0 I mapped this signals. In location1 I mapped
others signals for another device...
For controlling the motor I write in this ram some words at
location0. I choise to use a ram because I have more devices. I made
ram block dual port whith synchron write on port1 and asynchron read
on port2( on port1 I write command and on port2 I read signal
controls).
It is this best solution???? Have you another solution for me?
Please help me..
Thanks, |
