Detailed Description

AMBA-PV core transaction interface.

This is a tagged variant of the tlm::tlm_fw_transport_if interface. This interface is used for the forward path.

Note:

AMBA-PV slaves must implement the amba_pv_fw_transport_if interface.

virtual void amba_pv::amba_pv_fw_transport_if::b_transport	(	int	socket_id,
		amba_pv_transaction &	trans,
		sc_core::sc_time &	t
	)			[pure virtual]

Blocking transport.

Parameters:

	socket_id	socket identifier (ignored on the master side).
	trans	transaction.
	t	timing annotation.

Implemented in amba_pv::amba_pv_to_tlm_bridge< BUSWIDTH >, amba_pv::amba_pv_decoder< BUSWIDTH, NUMMASTERS, NUMSLAVES >, amba_pv::amba_pv_exclusive_monitor< BUSWIDTH >, amba_pv::amba_pv_memory_base< BUSWIDTH >, amba_pv::amba_pv_simple_probe< BUSWIDTH >, and amba_pv::amba_pv_slave_base< BUSWIDTH >.

virtual unsigned int amba_pv::amba_pv_fw_transport_if::transport_dbg	(	int	socket_id,
		amba_pv_transaction &	trans
	)			[pure virtual]

Debug access to a target.

This use the same path as the b_transport() interface. This debug access must be performed without any of the delays, waits, event notifications or side effects associated with a regular transaction. This debug access is, therefore, non-intrusive.

Parameters:

	socket_id	socket identifier (ignored on the master side).
	trans	transaction.

Returns:

number of bytes read or written or, if error, 0.

Implemented in amba_pv::amba_pv_to_tlm_bridge< BUSWIDTH >, amba_pv::amba_pv_decoder< BUSWIDTH, NUMMASTERS, NUMSLAVES >, amba_pv::amba_pv_exclusive_monitor< BUSWIDTH >, amba_pv::amba_pv_simple_probe< BUSWIDTH >, and amba_pv::amba_pv_slave_base< BUSWIDTH >.

virtual bool amba_pv::amba_pv_fw_transport_if::get_direct_mem_ptr	(	int	socket_id,
		amba_pv_transaction &	trans,
		tlm::tlm_dmi &	dmi_data
	)			[pure virtual]

Requests a DMI access based on the specified transaction.

Returns a reference to a DMI descriptor of type tlm_dmi that contains the bounds of the DMI region.

Parameters:

	socket_id	socket identifier (ignored on the master side).
	trans	transaction.
	dmi_data	DMI Descriptor.

Returns:

true if DMI access is granted, false otherwise.
