Methods, systems, and computer programs are presented for processing Ethernet packets at a Field Programmable Gate Array (FPGA). One programmable integrated circuit includes: an internal network on chip (iNOC) comprising rows and columns; clusters, coupled to the iNOC, comprising a network access point (NAP) and programmable logic; and an Ethernet controller coupled to the iNOC. When the controller operates in packet mode, each complete inbound Ethernet packet is sent from the controller to one of the NAPs via the iNOC, where two or more NAPs are configurable to receive the complete inbound Ethernet packets from the controller. The controller is configurable to operate in quad segment interface (QSI) mode where each complete inbound Ethernet packet is broken into segments, which are sent from the controller to different NAPs via the iNOC, where two or more NAPs are configurable to receive the complete inbound Ethernet packets from the controller.

Methods, systems, and computer programs are presented for distributing Ethernet packets at a Field Programmable Gate Array (FPGA). One programmable integrated circuit includes: an iNOC comprising iNOC rows and iNOC columns; a set of clusters coupled to the iNOC, each cluster comprising a vertical network access point (NAP) for iNOC column communications, a horizontal NAP for iNOC row communications, a valid signal, and programmable logic, where the vertical NAP is connected to the horizontal NAP when the valid signal is activated; and an Ethernet controller coupled to the iNOC, the Ethernet controller configurable to send Ethernet-packet segments to the vertical NAPs.
