Tsi148 PCI/X-to-VME Bus Bridge User Manual

4. The PCI-X Target sends a read request to the Linkage Module with the VME address
5. After arbitration, the Linkage Module command and address information is passed to a
6. The VME Master issues the read request to the VMEbus slave
7. The VME Slave satisfies the read request and the data is stored in one of the two, 4 Kbyte
8. Once the full byte count of the read request is satisfied and the data is queued in a VME
information and required byte count
— Tsi148 supports byte counts of up to 4 Kbytes
VME Master read buffer command queue.
VME Master read buffer data queues.
Master’s buffer, the VME Master makes a return request to the Linkage Module.
The Linkage Module provides a common interface for all the modules. The
Linkage Module interface has the following ports: VMEbus, PCI bus, DMA 0,
DMA1, and registers. The Linkage Module uses a round-robin arbitration scheme
to fairly arbitrate between the ports.
Having two buffers to store data allows the Tsi148, through the VME Master, to
do back-to-back reads on the VMEbus.
