Detailed Description

Unpack an event packet that includes an extra header inserted by the software.

This software-inserted-header is written in the read_event for the HcalBackplaneZCU target.

See also

ECONDEventPacket for how a single sample from a single ECOND is unpacked. The class contains the more complicated logic and is much more stable since the hardware/firmware on the ECOND is not liable to change as quickly and the firmware/software we are writing for LDMX.

Member Function Documentation

from()

void pflib::packing::SoftWrappedECONDEventPacket::from

(

std::span< uint32_t >

frame

)

unpack the given data into this structure

The software emulation adds another header before the ECOND packet, which looks like

4b flag | 9b ECON ID | 4b il1a | S | 0 | 8b length

• flag is hardcoded to 0b0001 right now in software
• ECOND ID is what it was configured in the software to be
• il1a is the index of the sample relative to this event
• S signals if this is the sample of interest (1) or not (0)
• length is the length of the econd subpacket NOT including this header

read()

Reader & pflib::packing::SoftWrappedECONDEventPacket::read

(

Reader &

r

)

read into this structure from the input Reader

DANGER Without signal trailer words, this assumes that the data stream is word aligned and we aren't starting on the wrong word.
