QOSC4B through QOSC52 represents the set of WFQ parameters (see section 7.5) for Gigabit port 3. The
granularity of the numbers (bits [5:0]) is 1, and their sum must be 64. QOSC4B corresponds to W0, and QOSC52
corresponds to W7.
Class 6 Shaper Control Port G0
10.6.79 QOSC73 - TOKEN_RATE_G0
Serial Interface Address:h58A
Bits [7:0]
•
Bytes allow to transmit every frame time (0.512usec) when regulated by
Shaper logic. (Default: 8'h08)
10.6.80 QOSC74 - TOKEN_LIMIT_G0
Serial Interface Address:h58B
Bits [7:0]
•
Bytes allow to continue transmit out when regulated by Shaper logic.
(16byte/unit) (Default: 8'hC0)
QOSC73 and QOSC74 correspond to parameters from section 7.6 on the shaper for EF traffic. QOSC73 is an
integer less than 64, with granularity 1. QOSC74 is the programmed maximum value of the counter (maximum burst
size). This value is expressed in multiples of 16. QOSC73 and QOSC74 apply to Gigabit port 0. Register
QOSC39-CREDIT_C6_G0 programs the peak rate. See QoS application note for more information.
