Jagiellonian University

2. TRB3 and GbE Single link, plug and play communication
Readout and slow control
HADES data packer
TrbNet-Over-GbE
Network discovery
Protocols multiplexing
DHCP, ARP, ICMP, UDP, TCP(bypass)
64k UDP packet construction
Single Ethernet frames receivers
Frames reassembly foreseen
112MBps on constant transmission

3. TRB3 and GbE Multiple links on TRB3
Single quad turned into independent GbE links
Modular and generic-configurable GbE module
Various protocols
Various buffer sizes
More flexible implementation
Separation of slow control and readout - more responsive operation
Multiple readout channels – larger throughput

4. Trb3 and GbE

5. GbE on other platforms Implemented on various range of devices
Xilinx: V4, V5, Kintex
Compute Nodes v2,3
FAZIA VME module
Kintex Development Board (evaluation)
Zynq PET Central Controller (to be done)
Lattice: ECP2, ECP3
Easy and standarized implementation of custom protocols over UDP
Module applicable for:
Hardware evaluation
Logic debugging purposes
Registers IO

6. Central Controller Hardware features: TRB3 form factor
Xilinx Zynq 7045
16x 12,5 Gb SFP
2GB of DDR3
RJ45 Ethernet (ARM)
USB (ARM)
SD (design storage)
8x RJ45 general purpose
TRB3 form factor

7. Central Controller
Board in the middle – between TRBs and Event Builders
For reduced size setups
Event based reception and parsing of the data from TRB3
GbE used as transport protocol
Up to 16 paralel inputs
Unpack the TDC Times and channel numbers
Ordered storage in DDR memory
Online
Filtering (coincidence, multiplicity etc.)
Histograming
Event building and unpacking
Memory shared with ARM
Construction of high-level data structures

8. Outlook Evaluate multilink GbE on TRBv3
Migrate to some softcore MAC implementation
Migrate to Kintex7 and Zynq
Evaluate the 10GbE
