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
