The Network-on-Chip Interconnect is the SoC

March 25th, 2021 - By Benoit de Lescure

The NoC interconnect is the SoC architecture.

“The network is the computer,” coined by John Gage of Sun Microsystems back in 1984, proved incredibly insightful. This idea is re-emerging, this time within the SoC realm. Functions in a chip that communicate with each other—not through simple wires but through complex network elements such as switches, protocol converters, packetizers, and so on—are not so different from the set of computers communicating through a network within a cabinet, or a room, back in 1984.

IP Transaction Protocols: Plug and Play AMBA, OCP and others

As engineers, we view transaction protocols as simply a language to be able to communicate information from one block of system-on-chip (SoC) IP to another block. However, if you look at transaction protocols from an economics framework you see there’s much more to it. With the past interconnect fabrics dominated by crossbars and hierarchal busses, the choice of the IP transaction protocol created a humongous switching cost.

Busses, Crossbars and NoCs: The 3 Eras of SoC Interconnect History

Today the processor in your Blackberry or iPhone has more calculating power than a PC did only a decade ago. No surprise here. But how did this happen? What enabled this?
