PAICORE NoC IMPLEMENTATION

Description

This project implements a five-level up-down quadtree Network-on-Chip (NoC) with multiple upstream and downstream datapaths, based on the PAICORE architecture.

NoC features

GALS (Globally Asynchronous, Locally Synchronous) design style
Use of Address Event Representation (AER)
Supports two packet types: normal and payload
Capable of unicast and multicast communication

Reminder for Router L1

FIFO0 -> DS4 -> Pos 11 FIFO1 -> DS3 -> Pos 10 FIFO2 -> DS2 -> Pos 01 FIFO3 -> DS1 -> Pos 00 FIFO4 -> U -> Upstream FIFO5 -> U -> Upstream
