Example VME Slave Write Transaction
In this example VME-to-PCI/X write transaction, the data passes through Tsi148 through the
VME Slave, to the Linkage Module, and ends at the PCI/X Master. The following list, and
Figure
1. A VMEbus master initiates a write to a PCI/X target.
2. The VME Slave queues the address and command information within its write buffer
command queue. The command queue is six entries deep.
— All write transactions are posted within the VME Slave’s write buffer data queue.
— The VME Slave’s write buffer data queue is 4 Kbytes.
8, show the steps taken in the write transaction.
