Multicore Communication

Collection of different communication methods for chip mulitprocessors.

This repo shall include all the multicore communication we have done in T-CREST as a standalone repo to make the work more useful.

Currently we plan to use a simple rd/wr/address/data/rdy interface, which maps dirctly to the Patmos OCPcore interface (A command is acked in the next clock cycle or later, IO devices need to be ready to accept a command during the ack cycle).

The S4NOC has currently a slightly different interface (no rdy needed).

We may consider moving to AXI.

Usage

This project is published iwth Maven Central. Add following line to your build.sbt

libraryDependencies += "io.github.t-crest" % "soc-comm" % "0.1.1"

Dependency

This project depends on ip-contributions, which is resolved in build.sbt

Setup

The hardware is described in Chisel and needs just a Java JDK (version 8) and sbt installed. All other needed packages will be automatically downloaded by sbt.

On a Mac with OS X sbt can be installed, assuming using homebrew as your package management tool, with:

brew install sbt

On a Debian based Linux machine, such as Ubuntu, you can install sbt with:

echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 \
  --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt

For the Chisel based tests compiler with gcc like interface is needed.

Projects

S4NOC

The network interface and the S4NOC are written in Chisel and the source can be found in s4noc

The tests can run from the current folder with a plain

sbt test

or from your favorite Scala IDE (e.g., InelliJ or Eclipse).

To generate the Verilog code with a traffic generator execute

sbt "runMain s4noc.S4nocTrafficGen n"

where n is the number of cores.

The generated Verilog file can be found in generated/S4nocTrafficGen.v and can be synthesized to provide resource numbers and maximum clocking frequency. An Intel Qartus project is available in quartus.

TODO

  • Do a simple multicore device (no communication, just a register and core number) and integrate it with T-CREST
    • A multicore "Hello World"
  • drop iotester dependency
  • s4noc: Have the core # to slot # mapping in HW (it should be cheap)
  • s4noc: Play with FIFO buffer variations
  • Do traffic generators like in the Dally book
  • Have a better defined CPU interface, with one cycle latency here not in OCP wrapper
  • Provide blocking in the CPU interface if not data available or TX FIFO full
  • Get the Chisel 2 NoC running

Next Paper

  • Build a standard NoC router for best effort
