Difference: ComputeNode (r8 vs. r7)

Compute Node Overview

An FPGA-based computational node for PANDA, BESIII and HADES.

For information about old and deprecated versions of the Compute Node, please refer to this page.

Compute Node Version 3 (CNv3):

Motherboard

The so called Compute Node(CN) Node (CN) is foreseen as the FPGA FPGA-based based hardware component of the PANDA DAQ. The third revision of the CN is an ATCA (advanced Telecommunication (Advanced Telecommunications Computing Architecture) based carrier board. It is able to carry hold up to 4 xFP boards. The CN is equipped with a Xilinx Virtex 4 FX60, FX60 as a switching FPGA to connect the xFP boards in an intelligent way to the backplane. It supplies also supplies direct high speed communications between these boards via rocked I/O. Rocked IO.

Daughterboard (xFP)

A An xFP board is an extended Extended Telecommunications Computing Architecture (xTCA) compliant board. It is a an FPGA based board with a ╬╝TCA form factor, compliant board featuring a Xilinx Virtex 5 FX70T-2 FPGA, 4 GB DDR2, DDR2 RAM, 1Gb Ethernet, and 4 SFP+ (Small Form- Form Factor Pluggable) cages. These cages can be equipped for example with optical or RJ45 interfaces.
