5.1.9.2. Burst Adaptation: AXI to Avalon®
The following entries specify the behavior when converting between AXI and Avalon® burst types.
Burst Type |
Behavior |
---|---|
Incrementing | Sequential Subordinate Bursts that exceed slave_max_burst_length are converted to multiple sequential bursts of a length less than or equal to the slave_max_burst_length. Otherwise, the burst is unconverted. For example, for an Avalon® agent with a maximum burst length of 4, an INCR7 burst is converted to INCR4 + INCR3. Wrapping Subordinate Bursts that exceed the slave_max_burst_length are converted to multiple sequential bursts of length less than or equal to the slave_max_burst_length. Bursts that exceed the wrapping boundary are converted to multiple sequential bursts that respect the Avalon® agent's wrapping boundary. |
Wrapping | Sequential Subordinate A WRAP burst is converted to multiple sequential bursts. The sequential bursts are less than or equal to the max_burst_length and respect the transaction's wrapping boundary Wrapping Subordinate If the WRAP transaction's boundary matches the Avalon® agent's boundary, then the burst passes through. Otherwise, the burst is converted to sequential bursts that respect both the transaction and Avalon® agent wrap boundaries. |
Fixed | Fixed bursts are converted to sequential bursts of length 1 that repeatedly access the same address. |
Narrow | All narrow-sized bursts are broken into multiple bursts of length 1. |
