Detailed Description

Declaration of FSIN routers.

Define Documentation

#define address	(		cx,
			cy,
			cz
	)		(cx + cy*nodes_x + cz*nodes_x*nodes_y)

Given the coordinates X,Y,Z of a node, returns the node identifier. Only valid for mesh-like topologies.

#define dir	(		j,
			k
	)		((j*nways) + k)

Calculates the port asigned to a direction pair (dimension, way ).

Parameters:

j	dimesion.
k	way.

#define port_address	(		p,
			c
	)		((p*nchan) + c)

Given a port and VC, returns channel identifier.

Parameters:

p	port.
c	VC.

Typedef Documentation

typedef enum bet_type bet_type

An type, related to dim, used to bet in which direction I'll try to make a request for reservation of a VC; it includes "-1" to denote the Escape VC

typedef long channel

A type to enumerate channels -- actually a long

typedef enum dim dim

An enumeration to define dimensions X, Y and Z channels. When used with ports, possible values are also INJ (injection) and CON (consuption).

typedef enum multistages multistages

An enumeration to define multistage coordinates

typedef struct port port

Structure that defines a pair of input - output ports.

typedef long port_type

A type to enumerate ports -- actually a long

typedef struct router router

Structure that defines a network router. Includes input buffer, transit queues and many auxiliary data structures.

typedef enum way way

An enumeration to define the "UP" or "+" way, and the "DOWN" or "-" way

---

Enumeration Type Documentation

enum bet_type

An type, related to dim, used to bet in which direction I'll try to make a request for reservation of a VC; it includes "-1" to denote the Escape VC

enum dim

An enumeration to define dimensions X, Y and Z channels. When used with ports, possible values are also INJ (injection) and CON (consuption).

enum multistages

An enumeration to define multistage coordinates

enum way

An enumeration to define the "UP" or "+" way, and the "DOWN" or "-" way

Enumerator:

UP	In X: left -> right; in Y, down -> top; increasing values.
DOWN	In X: left <- right; in Y, down <- top; decreasing values.
