Contributor Van Leuken, T.G.R.M.

Inspection devices are sent through the lines to record sensor data, this data needs to be post-processed in order to be able to make an analysis on the state of the pipeline. In this thesis, existing software implementations of post-processing algorithms are taken and implemented in VHDL code. This code is synthesizable for implementation in a field programmable gate array (FPGA). Goal is to reduce the time require for post-processing. A test environment is implemented which is able to feed data to the FPGA and receive the processed data back. This environment consists of a Linux PC, which communicates in DMA mode over the PCI-Express bus to the FPGA. The test environment is functional, it shows a performance increase of eight to fourteen times compared to the software implementation. A proposal is made for speeding this up even more, by using concurrent processing on multiple processing nodes.
