TMC01 Moduls (Token-Mesh Converter) for the Foxboro PLS80E System-Bus connect redundant Controllers CM23 and CX21 with the Mesh Control Network. Overview

The Foxboro PLS80E Automation system depends on the established Eckardt PLS 80 System and will be continuously upgraded, according to the commitment of Invensys to customers for life cycle support. Invensys utilises Mesh Control Networks for Automation-Systems.
By this way now the PLS80E Token-Bus System will be upgraded to a state-of–the-art Ethernet Mesh Control Network.
The Mesh Control Network replaces both the PLS80E System-bus and the PLS80E Function-bus. To this Bus the new controllers CX22 will be direct connected.

The TMC01 is designed to connect also the older controllers PLS 80E controller CX21 and CM21 to the Mesh Network and therefore to integrate older modules with new components for a sufficient life cycle concept. TMC01 modules replace plug-compatible previous necessary bus connectors and can also used in redundant configurations.
The TMC01 modules start automatically after plug-in on the system-rack, no configurations are necessary. Replacement will be done on-line. Software Updates for the TMC01 will be done ‘remote and on-line’ from an Engineering station.

Together with a Mesh Control Network there are also available network-monitors as Nagios or similar.
These functions not only control cyclic the Mesh Control Network, but also the communication level of the connected controllers. By this way preventive maintenance will be possible.

MESI Coherency InterSection Controller

Description
The MESI InterSection Controller (ISC) is a coherence system controller. It supports the MESI coherence protocol for a cache data consistency. It synchronizes the memory requests of the system masters. It enables to keep the consistency of the data in the memory and in the local caches. This project provides the following elements:

1. A synthesizable controller core with a complete environment of verification, synthesis, and documentation.
2. Instructions for integrating MESI_ISC to a system.
3. A definition and requirements of the system masters.


Project status:
- Documentation: On progress. Main chapters have written.
- RTL: Done.
- Verification: On progress. A basic test plan has done.

PCI card with Xilinx X3CS500E
The card is a PCI card. Tested in 2 different PC(1 old intel and 1 recent AMD FX 64bits) , with 2 different PCI core (Raggedstone and mini-pci). The card connect 50 PCI signals and can theorically handle all feature of the PCI bus (bus master, interrupts etc). The FPGA used XC3S500E is very large and the PCI core currently use 2% of LUT space. The card is basically designed from the Raggedstone V1 design from Enterpoint LTD (same bus switch, roughly same PCI connections). The PCB is professionnaly manufactured , but the card is soldered by my hands. 3 units are currently assembled. They is spare PCB available for anyone interested.All the electronic components are available from Digikey or Mouser except for the Xilinx FPGA.

RapidIO IP library
This project contains a collection of IP cores that can be used to build RapidIO 2.2 capable devices, for example an end point, a switch or a switch with internal endpoints. All IP cores was initially developed in an internal project at Bombardier that agreed to release it to the general public.

Below are brief descriptions of the existing IP cores that are currently available and some that will be available in a near future.

RioSwitch.vhd
This IP core implements RapidIO packet switching between a configurable number of ports. It can receive and process maintenance packets to do basic switch configuration.
Status: Available

RioPacketBuffer.vhd
This IP core implements a RapidIO packet queue. It can store a configurable number of packets in a configurable sized memory.
Status: Available

RioSerial.vhd
This IP core implements RapidIO LP-serial Physical Specification, but only the transmission independent protcol parts. This allows the development of custom PCS layers that does not follow the standard and that can use an existing legacy communication infrastructure.
Status: Available

RioPcsUart.vhd
This IP core implements a PCS (Physical Coding Sublayer) that uses an 8-bit UART as its transmission channel. It can be used by the RioSerial IP module to send RapidIO packets over a standard 8-bit, no parity, 1 stop bit, UART. It has some similarities to PPP.
Status: Will be posted soon.

RioWbBridge.vhd
This IP core implements a bridge between a RapidIO network and a Wishbone bus. It acts as a RapidIO slave endpoint and accepts NWRITE and NREAD packets that are converted into Wishbone accesses. It can be attached to a RioPacketBuffer IP module which in turn is connected either interfacing a RioSwitch (switch with local end point) or interfacing RioSerial (stand alone end point).
Status: Will be posted soon.

RioPcsRmii.vhd
This IP core implements a PCS (Physical Coding Sublayer) that uses an ethernet PHY as its transmission channel. It can be used by the RioSerial IP module to send RapidIO packets over a standard ethernet cable.
tatus: Under development.

RioEthBridge.vhd
This IP core implements a bridge between an ethernet network and a RapidIO network. It emulates an ethernet PHY with an RGMII interface to make it directly attachable to a processor with an internal ethernet MAC. A RapidIO packet is encapsulated in an ethernet packet with a special ethernet type. It can be attached to a RioPacketBuffer and a RioSwitch or RioSerial depending on the specific need.
Status: Under development.


C-code

riostack.c
This C-code contains an implementation of RapidIO LP-serial Physical Specification, but only the transmission independent protocol parts. The C-code is written without using any OS-libraries and can be integrated into any microcontroller. It requires a custom symbol codec between the transmission channel and the lower parts of the C-stack implementation. It also requires an upper-half to interface a user application or an operating system. It has been successfully integrated into a Linux device driver and a small micro controller running FreeRTOS. It has two compiling options, non-transparent and transparent. The non-transparent answers received maintenance request packets automatically and is inteded for a normal end point implementation. If the transparent option is used, all maintenance requests are passed to upper parts of the stack. This makes it possible to, for example, simulate a switch or to emulate a full RapidIO network in software.
Status: Will be posted soon.

riocodecuart.c
This C-code contains an implementation of a symbol codec that can handle a data stream generated by the IP core RioPcsUart. It is provided as an example and needs to be integrated into a custom codec suitable for the target processor.
Status: Will be posted soon.

Fade - Light L3 Ethernet protocol for transmission of data from FPGA to embedded PC
This project implements the simple and light protocol for transmission of data from low resources FPGA connected to the Ethernet MAC and an embedded system running Linux OS. The main goal was to assure the reliable transmission over unreliable Ethernet link without need to buffer significant amount of data in the FPGA. This created a need to obtain possibly early acknowledgment of received packets from the embedded system, and therefore the protocol had to be implemented in layer 3.

Development status: Beta
