# Frequently Asked Questions
|
|
|
|
|
|
Q: Does the core support RORA mode (Release on Register Access)?
|
|
|
The core does not support the RORA mode.
|
|
|
Furthermore note that the Interrupter implemented has not a queue.
|
|
|
You can implement a queue in your WB application and output a new
|
|
|
interrupt request only after a read operation.
|
|
|
This will be the equivalent of a RORA Interrupter.

|
Q:In which FPGA is it possible to fit the vme64x core?
|
|
|
We are testing the core in the following FPGA:
|
|
|
|
|
|
\- Spartan 6
|
|
|
Device: XC6SLX150T
|
|
|
Package: FGG676
|
|
|
Speed -3
|
|
|
|
|
|
\- Spartan 6
|
|
|
Device: XC6SLX150T
|
|
|
Package: FGG900
|
|
|
Speed -3
|
|
|
|
|
|
You can also fit the vme64x core in a smaller FPGA like the Spartan 6
|
|
|
XC6SLX9, package: FTG 256.
|
|
|
It depends on your WB application.
