4.2.5 AMBAPVACE2PVBus component
This section describes the AMBAPVACE2PVBus component.
AMBAPVACE2PVBus - about
This component converts from AMBAPVACE to PVBus protocols.
This is a LISA+ component.
AMBAPVACE2PVBus - ports
This section describes the ports.
Table 4-7 AMBAPVACE2PVBus ports
||AMBAPVACE||Slave||Slave port for connection from top-level AMBAPVACE slave port. Handles incoming transactions from AMBA-PV ACE masters. Converted upstream ACE snoop and DVM transactions are sent out through this port.|
||PVBus||Master||Converted downstream transactions are sent out though this port. Handles incoming ACE snoop and DVM transactions from PVBus slaves.|
AMBAPVACE2PVBus - debug features
This component supports debug bus transactions but has no specific debug features.
AMBAPVACE2PVBus - verification and testing
This component passes system level tests that included booting Linux on an ARM® big.LITTLE™ VE platform.
AMBAPVACE2PVBus - performance
The translation of bus transactions by the bridge has some impact on performance. Bus masters that cache memory transactions avoid much of this impact. The bridge does not support DMI.
AMBAPVACE2PVBus - library dependencies
This component depends on the AMBA-PV API, which must be at least version 1.4.
