[fpc-pascal] Realtime and freepascal???

The brief description of your project suggests that it may not need "hard
real-time" , since you are planning to write to flash memory or send the
data over an RF link. Hard real-time usually implies receiving input data
and responding with an output control in a timely and predictable manner. 

Your application seems more like data logging where you don't want to lose
any data , and in that case Linux will suffice if you use a 1Gbps Ethernet
link which I have tested using Synapse and handles data at roughly 800Mbps
using Free Pascal.

If you have access to hardware such as FPGA , or some special hardware ,
then preconditioning the data using buffers removes the need for hard
real-time and Free Pascal running under vanilla Linux will more than
suffice.
