Running pRUParser

Software Function

The pRUParser takes a raw, binary, offload stream of pRU data from a file created by the pDTP Client. It will sort, error check and prunes this in to a raw, binary, stream and save this do disk for further prosessing. It will lastly print a summary of any errors it detected.

Protocol Dependencies

The pRUParser uses the pRU Data Format Specification v0.2

Usage

In the readout/ folder in your build directory: For help run: <syntaxhighlight lang="bash"> $./run-pru-parser -h </syntaxhighlight>

To parse a file, run: <syntaxhighlight lang="bash"> $./run-pru-parser -i relative/path/to/input/file -o relative/path/to/output/file -v verbosity level (0 or 1) </syntaxhighlight>

Output

During the parse, status summaries will be printed: <syntaxhighlight lang="bash"> Starting pipeline ... Input policy [File reader]: file readout/testDataX288.bin size kxcd Filter policy [Forward]: buffer of kxcd byte(s) This parse had a speed of: 672.798 Mb/s Ouput policy [File writer]: write to file readout/pData.bin size kxcd ... done </syntaxhighlight>

Then a summary is printed: <syntaxhighlight lang="bash"> SUMMARY ------------- Total number of pRU frames parsed: n Total number of pRU empty words found: n Total number of pRU delimiter words found: n Unfinished pRU words in buffer: n </syntaxhighlight>

If any pRU empty words are received a shot summary will be printed: <syntaxhighlight lang="bash"> EMPTY FRAMES FOUND: n </syntaxhighlight>

If no errors are found, this will be printed: <syntaxhighlight lang="bash"> No errors found. </syntaxhighlight>

Otherwise an error summary will be printed: <syntaxhighlight lang="bash"> INPUT_SIZE_ERROR: n, MULTIPLE_PRU_HEADER_ERROR: n, DATA_WORD_MISSING_HEADER_ERROR: n, TRAILER_WORD_MISSING_HEADER_ERROR: n, PRU_TRAILER_FLAGS_ERROR: n, NO_DATA_WORD_ERROR: n, FRAME_SIZE_ERROR: n, MISSING_CHIP_HEADER_ERROR: n, MISSING_REGION_HEADER_ERROR: n, MISSING_CHIP_TRAILER_ERROR: n, MULTIPLE_CHIP_HEADER_ERROR: n, ALPIDE_TRAILER_FLAGS_ERROR: n, PADDING_ERROR: n, UNKNOWN_ALPIDE_WORD_ERROR: n </syntaxhighlight>

If any of the non fatal alpide trailer flags has been detected, a summary will be printed: <syntaxhighlight lang="bash"> ALPIDE Busy Transition: n ALPIDE Strobe Extended: n </syntaxhighlight>
