AMBAPVValueState
Allows a master to retrieve the current value from a slave, using 32 bit integer
values. See AMBAPVValueState protocol on page 5-22.
AMBAPVValueState64
Allows a master to retrieve the current value from a slave, using 64 bit integer
values. See AMBAPVValueState64 protocol on page 5-22.
There are ready-to-use components that provide you with conversions between PVBus and
AMBAPV protocols as well as between Signal and AMBAPVSignal protocols, StateSignal and
AMBAPVSignalState, Value(_64) and AMBAPVValue(64), and ValueState(_64) and
AMBAPVValueState(64) protocols. There are examples of use of the AMBA-PV components
in %PVLIB_HOME%\examples\SystemCExport. On Linux, the examples can be found in
$PVLIB_HOME/examples/SystemCExport.
For more detail on the PVBus protocols and components, see PV Bus components on page 5-3.
The protocols and components are designed to interface with the AMBA TLM PV library for
OSCI TLM 2.0. This library is delivered with Fast Models and is intended to providing a
standard way of mapping the AMBA protocol on top of OSCI TLM 2.0 kit at PV level.
For details of the AMBA TLM PV library for OSCI TLM 2.0 1 kit, refer to the documentation
provided with Fast Models in %MAXCORE_HOME%\AMBA-PV\doc. On Linux, use the $MAXCORE_HOME
environment variable instead.
For details of the OSCI TLM 2.0, refer to the documentation provided with the kit. This can be
downloaded from the OSCI web site. See http://www.systemc.org.
5.3.2 AMBA-PV component protocols
The AMBA-PV component protocols are:
• AMBAPV protocol
• AMBAPVSignal protocol on page 5-21
• AMBAPVSignalState protocol on page 5-21
• AMBAPVValue protocol on page 5-21
• AMBAPVValue64 protocol on page 5-21
• AMBAPVValueState protocol on page 5-22
• AMBAPVValueState64 protocol on page 5-22.
AMBAPV protocol
The AMBAPV protocol defines behaviors for single read and single write transactions. This
covers AMBA3 AXI, AHB and APB bus protocol families, all at the PV level. In addition, the
AMBAPV protocol provides support for AMBA protocol additional control information,
including:
• protection units
• exclusive access and locked access mechanisms
• system-level caches.
The behaviors of the protocol are:
read()
Completes a single read transaction at the given address for the given size in
bytes. Additional AMBA protocol control information can be specified using the
ctrl parameter. The socket_id parameter must be set to 0 in this context.
