EGRESS_BYPASS
• Title: Egress Bypass
• Category: Ring Bound Enhancement
• Event Code: 0x40, Max. Inc/Cyc: 1,
• Definition: Egress Bypass optimization utilized.
• NOTE: Enabling multiple subevents in this category will result in the counter being increased by the
number of selected subevents that occur in a given cycle. Because only one of the even/odd FIFOs
can arbitrate to send onto the ring in each cycle, the event for the even/odd FIFOs in each direction
are exclusive. The bypass event for each direction is the sum of the bypass events of the even/odd
FIFOs.

EGRESS_STARVED
• Title: Egress Cycles in Starvation
• Category: Ring Bound Credits
• Event Code: 0x43, Max. Inc/Cyc: 1,
• Definition: Number of cycles the S-Box egress FIFOs are in starvation.
• NOTE: Enabling multiple subevents in this category will result in the counter being increased by the
number of selected subevents that occur in a given cycle. Because only one of the even/odd FIFOs
can arbitrate to send onto the ring in each cycle, the event for the even/odd FIFOs in each direction
are exclusive. The bypass event for each direction is the sum of the bypass events of the even/odd
FIFOs.
