Detailed Description

Wormhole Router with virtual channels.

Template Parameters

NumLPorts	Number of local ingress/egress ports
NumRports	Number of remote ports
NumVchannels	Number of virtual channels
BufferSize	Buffersize of input fifo
FlitType	Indicates the Flit type
MaxHops	Indicates Max. number of hops for SourceRouting

A Simple Example: #include <WHVCRouter.h>
...
typedef Flit<64, 0, 0, 0, FlitId2bit, WormHole> Flit_t;
WHVCRouter<kNumLPorts, kNumRPorts, kNumVChannels, kBufferSize, Flit_t, kNumMaxHops> router;
Connections::In<Flit_t> in_port[kNumPorts];
Connections::Out<Flit_t> out_port[kNumPorts];
Connections::In<Credit_t> in_credit[kNumCredits];
Connections::Out<Credit_t> out_credit[kNumCredits];
for (int i = 0; i < kNumPorts; i++) {
router.in_port[i](in_port[i]);
router.out_port[i](out_port[i]);
for (int j = 0; j < kNumVChannels; j++) {
router.in_credit[i * kNumVChannels + j](
in_credit[i * kNumVChannels + j]);
router.out_credit[i * kNumVChannels + j](
out_credit[i * kNumVChannels + j]);
}
}
