Parallel For

Definition

If you use For outside of a Thread, the VHDL For is used. In that section you can repeat only a finite amount of times. If you want to use this parallel For in a thread, you have to write ParFor.

The for loop can count up (TO) or down (DOWNTO) between constant values. With exit; you can leave the loop before it is finished. The name of the counter (i) can be used as variable.

Examples

Process() {
For (i IN 7 DOWNTO 1)
{
LED(i) <= LED(i-1);
If(i = exitValue)
{
exit;
}
}
}

OR

Process() {
Thread {
ParFor (i IN 7 DOWNTO 1)
{
LED(i) <= LED(i-1);
If(i = exitValue)
{
exit;
}
}
}
}
