I am evaluating using FreeRTOS on a 486. I understand that FreeRTOS does not support FP  
as is. It appears to me that the only thing I  
need to modify is the context switch so that  
the floating point registers are preserved. Are there any other issues? I’m using a Borland 5.02  
development environment.

If you are using hardware floating point then that is ok, the registers need to be added to the context.&nbsp; If you are using software floating point then this is not the case as the Borland floating point libraries are not re-entrant.&nbsp;

There is some way of allocating a different area of memory to each task to hold the (non re-entrant) data.&nbsp; This could probably be found with a little googling.
