3.2. Interface attributes
The following tables list the master and slave interface attributes
for the bridge:
Table 2. Master interface attributes (continued)
| Attribute | Description | Value |
|---|
| Combined issuing capability | The maximum number of active transactions that
a master can generate | Master-dependent |
| Read ID capability | The maximum number of different ARID values that a master can generate
for all active read transactions at any one time | Master-dependent |
| Read ID width | The number of bits in the ARID bus | Master-dependent |
| Read issuing capability | The maximum number of active read transactions
that a master can generate | Master-dependent |
| Write ID capability | The maximum number of different AWID values that a master can generate
for all active write transactions at any one time | Master-dependent |
| Write ID width | The number of bits in the AWID and WID buses | Master-dependent |
| Write issuing capability | The maximum number of active write transactions
that a master can generate | Master-dependent |
Table 3. Slave interface attributes
| Attribute | Description | Value |
|---|
| Write acceptance capability | The maximum number of active write transactions
that a slave can accept. | Slave-dependent |
| Read acceptance capability | The maximum number of active read transactions
that a slave can accept. | Slave-dependent |
| Combined acceptance capability | The maximum number of active transactions that
a slave can accept. You must specify this if read and write address
storage is combined. | Slave-dependent |
| Write interleave depth | The number of active write transactions for
which the slave can receive data. This is counted from the earliest
transaction. | Slave-dependent |
| Read data reorder depth | The number of active read transactions for
which a slave can transmit data. This is counted from the earliest
transaction. | Slave-dependent |
Note
The master-dependent and slave-dependent values in the Value
column of Table 2,
and Table 3 indicate
that the bridge adopts the attribute value of the master or slave
that the interface is connected to.
