Detailed Description

Classes providing Protocol Packet Decoding capability.

Packet decoders convert incoming protocol packets from a packet processor, into generic trace elements to be output to an analysis program.

Packet decoders can be:-

• PE decoders - converting ETM or PTM packets into instruction and data trace elements
• SW stimulus decoder - converting STM or ITM packets into software generated trace elements.
• Bus decoders - converting HTM packets into bus transaction elements.

virtual

Default destructor.

Interface function to process a single protocol packet. Pass a trace index for the start of packet and a pointer to a packet when the datapath operation is OCSD_OP_DATA.

Parameters

op	: Datapath operation.
index_sop	: Trace index for the start of the packet, 0 if not OCSD_OP_DATA.
*p_packet_in	: Protocol Packet - when data path operation is OCSD_OP_DATA. null otherwise.

Returns

ocsd_datapath_resp_t : Standard data path response.

Implements IPktDataIn< P >.
