AGP3.0 Interface Specification
Rev. 1.0

The major change from AGP2.0 is that the number of source synchronous AD transfers that happen
within a common clock period has doubled. The timing parameters, t
1
, t
2
, and t
3,
have values different
from AGP2.0 to account for AGP3.0 signaling technology. The relationship between TRDY and the 8X
data transfer remains the same as the relationship between TRDY and the 4X data transfer that is in
AGP2.0. TRDY seen by the receiver after it is latched in cycle 2 means data will be available in cycle 3.
