Detailed Description

template<int DataWidth, int DestWidthPerHop, int MaxHops = 1, int PacketIdWidth = 0>
class Packet< DataWidth, DestWidthPerHop, MaxHops, PacketIdWidth >

Parameterized implementation of a network packet.

Template Parameters

DataWidth	Width of data field in a packet.
DestWidthPerHop	Number of bits required to encode destination field for one hop in a packet.
MaxHops	Maximum number of hops. For source routing, this field is used along with DestWidthPerHop field to calculate total width of destination field to be encoded in a packet. (default: 1)
PacketIdWidth	Width of packet id field. PacketID acts a an identified for every hop in a packet. (default: 0)

Overview

• Packet class is a generalized implementation of a network packet. Packet Format: <PACKET-ID>:<DEST>:<DATA>
• PacketID field is optional and can be removed by setting PacketIdWidth to 0.

A Simple Example

#include <nvhls_packet.h>
 
...
typedef Packet<PACKET_DATAWIDTH,DESTWIDTHPERHOP,MAXHOPS,PACKETIDWIDTH> Packet_t
Packet_t packet;
packet.data = 0xdeadbeef; // Initialize data
packet.dest = 0xde        // Set destination information for data 
    ...
