Hi, Remi,
(**) 4rd derives a port set from a PSID as shown in the picture below. I would implement it with masks and shifts rather than with multiplications and divisions and, in any case, without needing to think of any "Maximum number of contiguous ports" and a "Sharing ratio".: 4 : +---+----+---------+ Ports in the CE port set |> 0|PSID|any value| +---+----+---------+ : 16 : Cheers, RD
Note that if the ratio is bitwise, the multiplications and divisions are shift operations, and the module is mask operation. Therefore, no computational complexity is introduced.
