Ap_vld question

Jump to solution

Hello

 

I have a question about ap_vld

 

ap_vld
Creates an additional valid port (<port_name>_vld) to operate in conjunction with this
data port.
° For input ports, a read stalls the function until its associated input valid port is
asserted.

 

 

If i use these ports it stalls the function until the input valid port is asserted but wich data will go trough? The old one or the data that came when the valid port become asserted?

The data that is read is the data that is on the bus at the time ap_valid is asserted.
