Total throughput

(*) NOTE:  The The DEVIL alternately acquires e-, e +, e-, e +, ... and does only one update at a time. So As a consequence the throughput is not determined by the data volume of the 2 elements but by that of only one.

Example of LabVIEW code to use at level 1 to unflatten and extract the DCT Dyn DCTDyn and the array od 4096 DBL values. The DCTDyn cluster occupies 169 bytes, then 4096 DBLs follow.

LabVIEW data format

When using languages different from LabVIEW, the "unflatten from string" operator is not available; in these case, you have to decode the LV cluster made of the DCTDyn typeDef followed by the array of DBLs.

DCTDyn

The DCTDyn typeDef format is described below along with an example of its flattened string.

Array of DBL

Immediately after the DCTDyn it follows an array af DBL of 4096 components. In LabVIEW the array serialization is made by a U32 containing the number of components of the array and then the array itselsf.

Meaningful offsets

Be aware that the following offsets depends on the number of components of the "tau" array in the DCTDyn cluster.
