Function Documentation

void coords	(	long	ad,
		long *	cx,
		long *	cy,
		long *	cz
	)

Calculates the coordinates of a node (X, Y, Z)

Each node have stored their own coordinates because they are used often.

Parameters:

ad	Address of the node.
cx	Coordinate X is returned here.
cy	Coordinate Y is returned here.
cz	Coordinate Z is returned here.

router.rcoord

void coords_icube	(	long	ad,
		long *	cx,
		long *	cy,
		long *	cz
	)

Calculates the coordinates of a node (X, Y, Z) in a icube.

Each node have stored their own coordinates because they are used often.

Parameters:

ad	Address of the node.
cx	Coordinate X is returned here.
cy	Coordinate Y is returned here.
cz	Coordinate Z is returned here.

router.rcoord

void init_network

(

void

)

Initializes the network.

Gives the initial values to the simulation depending on the topology.

void init_ports

(

long

i

)

Initializes transit and injection ports of a node.

All port's structures (queues, arbitration, requesting, ...) are prepared for transit and injection ports of the given router.

Parameters:

i	The node whose ports must be initilized.

void router_init

(

void

)

Initializes all the routers in the network.

Prepares all structures needed for the simulation (routers & all their stuff for requesting, arbitring & stating). Event queues & occurred list are initilized here if compiled with the TRACE_SUPPORT != 0 .
