PXB 4330
Operational Description
Example:
Chosen values: R0 = 347000 cells/s (150 Mbit/s), SYSCLK = 50 MHz
with (5)â
T0 = 3----2--5---Ã0-----3Ã---4--1-7--0-0---6-0---0--= 4.50288â¦
thus with (6) and (7)â
IntRate = 4 and FracRate = 130 (rounded up)
Because of rounding the FracRate value, the effective scheduler rate R needs to be cal-
culated by solving equation (7) to T and equation (5) to R:
â
T = 1----3-2--0--5---6â-----1- + IntRate[T0]= 4.5039â¦
and
R = 3----2----5-Ã--0---4--Ã-.-5---1-0--0-3---6-9---â¦-----cellsâ1= 346921cellsâ1
