B
Backpressure
A condition where a channel is unable to accept new data, usually because its buffer is full.
Bridge
A module that connects a host to the network.
C
Channel
A set of wires that carry a particular type of data.
Channel Dependency Graph
A directed graph of all the dependencies in the network. A network is said to be deadlock free if its CDG is acyclic.
Clock Domain
A set of components that share the same clock source.
Component
A module that is part of the NoC. Usually a router or bridge, but sometimes an in-link module.
CSR
Configuration and Status Register
D
Deadlock
A condition where backpressure has propagated in a cycle, becoming self-sustaining.
Domain Crosser
A module that adapts between two clock domains.
F
Flow
The unit of mapping of traffic to the network. A flow is the set of all possible flits that are sent from one source to one destination.
H
Hop
One or more links that form a connection between a router/bridge and another router/bridge.
Host
A module that connects to the network through a bridge.
I
Interface
A set of channels that are used together to send and receive data.
K
KPI
Key Performance Indicator. A measurable metric used to evaluate the success, efficiency, or quality of the design process, performance, or output.
L
N
P
Packet
A set of flits that are sent together from one source to one destination. Packets are required to be transmitted non-interleaved and will be delivered non-interleaved.
Q
QoS
Quality-of-Service. It refers to the performance level and reliability of a system, network, or service, measured by specific metrics to ensure it meets user or application requirements.
R
RAS
Reliability, Availability, and Serviceability in data centers refers to a set of design principles and metrics ensuring systems operate reliably, remain available for use, and are easy to maintain or repair.
Router
A module that routes flits from input ports to output ports.
S
SoC
System-on-Chip. A chip that integrates an entire system onto it.
T
Transport
The functionality provided by the routers within a NoC: getting packets from one place to another.
V
Virtual Channel
A logical channel that allows a single physical channel to have independent backpressure for different packets.
