Abstract
Techniques described herein may relate to providing a programmable interconnect network (e.g., a programmable network-on-chip (NOC)). A method may include determining a transmission parameter, bonding one or more channels of an interconnect network based at least in part on the transmission parameter, and power-gating any unused channels after the bonding.
Claims20
A multi-die system, comprising:
- a processing circuit disposed on a first die;
- and
- a network-on-chip disposed at least in part on the first die, wherein the network-on-chip is configurable to facilitate memory transactions between the first die and a second die, wherein the network-on-chip comprises a plurality of data channels, wherein a first subset of data channels of the plurality of data channels are configurable to transmit data between portions of the processing circuit via the network-on-chip, and wherein a second subset of data channels of the plurality of data channels are configurable to transmit data between the first die and the second die.
A method, comprising:
- operating a programmable interconnect network at a first data width, wherein the programmable interconnect network is configurable to span multiple die of a same package;
- reprogramming a first data channel of the programmable interconnect network;
- and
- operating a subset of the programmable interconnect network at a second data width lower than the first data width, wherein the second data width excludes a width of the first data channel.
1 more element
An integrated circuit, comprising:
- a first set of channels of a plurality of channels of a network-on-chip;
- and
- a second set of channels of the plurality of channels, wherein the second set of channels and the first set of channels are configurable to facilitate communication between a first die and a second die.
