Constructor & Destructor Documentation

torc::bitstream::VirtexPacket::VirtexPacket ( void ) [inline]

Null constructor.

Definition at line 108 of file VirtexPacket.hpp.

torc::bitstream::VirtexPacket::VirtexPacket	(	uint32_t	inHeader,
		uint32_t	inCount,
		uint32_t	inWord,
		uint32_t *	inWords
	)			`[inline]`

Full constructor.

Definition at line 111 of file VirtexPacket.hpp.

torc::bitstream::VirtexPacket::VirtexPacket	(	uint32_t	inHeader,
		uint32_t	inWord
	)			`[inline]`

Header plus single word constructor.

Definition at line 117 of file VirtexPacket.hpp.

torc::bitstream::VirtexPacket::VirtexPacket ( uint32_t inHeader ) [inline]

Header only constructor.

Definition at line 122 of file VirtexPacket.hpp.

Member Function Documentation

static VirtexPacket torc::bitstream::VirtexPacket::read ( std::istream & inStream ) [inline, static]

Read a packet.

Todo:: we should throw an exception on invalid packet types

Definition at line 134 of file VirtexPacket.hpp.

void torc::bitstream::VirtexPacket::write ( std::ostream & inStream ) const [inline]

Write a packet.

Definition at line 176 of file VirtexPacket.hpp.

static VirtexPacket torc::bitstream::VirtexPacket::makeNullType1Write ( uint32_t inAddress ) [inline, static]

Construct a null type 1 write packet.

A type 1 write packet to the FDRI register is generally only useful to specify the current register in preparation for a type 2 write. The type 2 write header includes a size but specifies no target register, hence the prior null type 1 packet.

Definition at line 188 of file VirtexPacket.hpp.

static VirtexPacket torc::bitstream::VirtexPacket::makeType1Write	(	uint32_t	inAddress,
		uint32_t	inWord
	)			`[inline, static]`

Construct a type 1 write packet.

Definition at line 192 of file VirtexPacket.hpp.

static VirtexPacket torc::bitstream::VirtexPacket::makeType2Write	(	uint32_t	inCount,
		uint32_t *	inWords
	)			`[inline, static]`

Construct a type 2 write packet.

Definition at line 196 of file VirtexPacket.hpp.

static uint32_t torc::bitstream::VirtexPacket::makeHeader	(	EPacketType	inType,
		EOpcode	inOpcode,
		uint32_t	inAddress,
		uint32_t	inCount
	)			`[inline, static]`

Construct a packet header.

Todo:: Generate an error or throw an exception on invalid packet types?

Definition at line 209 of file VirtexPacket.hpp.

Definition at line 240 of file VirtexPacket.hpp.

uint32_t torc::bitstream::VirtexPacket::getWordSize ( void ) const [inline]

Returns the total number of words in the packet, including the header word.

Definition at line 242 of file VirtexPacket.hpp.

brief Returns the raw packet words, including the header word.

Definition at line 244 of file VirtexPacket.hpp.
