I read the following paragraph from “on-chip networks” book: “Inoff-chip networks, channel widths are limited by pin bandwith; this limitation causes flits to be broken down into smaller chunks called phits. To date, in on-chip networks, flits are composed of a single phit and are the smallest subdivision of a message due to wide on-chip channels.”
“In some networks the flit size equals the phit size and thus, there is no need to split into smaller phits.” How I can know it for alpha processor? Yes, I want to have some links to be wider. Do I need break flits into phits For adding multiple links in topology file?
