PCI Express Performance Meter

 Webshop Pricelist

Based on long years of experience with high speed data transfers we developed together with the University of Karlsruhe the PCIe Performance Meter.
The PPM is mainly developed to measure on an Hpe_IRP2 platform the transfer performance between FPGA and the processors.
The data logger is still an IP and can be used in every FPGA, at the moment we support Altera FPGA's.

Gives a true picture of the load of every PCIe lane

  • Can log up to 4 lanes
  • Time tick for measurement 1 ms
  • Data logging up to 100 hours
  • Data logs (per time tick) for :
    • - No. of Transaction Layer Packets
    - Amount of Payload
    - Amount of Header and Payload
    - Min. and Max. Payload
    - Software position number
    - Current of CPU, FPGA IO, FPGA core, Transceiver
  • Easy analysis of overloads during long program runs.
