ALICE is one of four large detectors situated at the collision points in the Large Hadron Collider (LHC) at CERN. The BusyBox is used by four of ALICE’s sub-detectors: Time Projection Chamber (TPC), Photon Spectrometer (PHOS), Forward Multiplicity Detector (FMD) and Electromagnetic Calorimeter (EMCal)

Triggers initiate data readout from ALICE’s sub-detectors and are received by the DCS board via an optical cable interface. The triggers and associated data are routed from the TTCrx ASIC on the DCS board to the BusyBox FPGA(s). Here, the L1a and Serial B line raw data is decoded by the Trigger Receiver firmware module.

Every time a trigger sequence starts the Fee starts buffering data, i.e. a buffer in the Fee is used. A valid trigger sequence ends with an L2a trigger and the event data along with the event ID is sent to the D-RORCs.

The purpose of BusyBox is to let the Central Trigger Processor (CTP) know when the Fee’s buffers are full by asserting a busy signal which prevents further issuing of triggers. The BusyBox and D-RORCs receives a unique event ID from the Fee after an event. After a valid trigger sequence ends the BusyBox will ask the D-RORCs if they have received the same event ID as the BusyBox did. If they do not reply with the same ID it means data has not been shipped from the Fee to the D-RORC, hence, the buffer in the Fee still holds event data.

The Fee buffers can hold 4 or 8 events and the BusyBox keeps track of free buffers. The busy is asserted if the buffers are full.

Interaction with the BusyBox is done through the DCS board, either via Ethernet or UART.

The BusyBoxes are located in the DAQ counting rom.

== Overview ==

Traditionally the Fee in ALICE sub-detectors indicates when its buffers are full and cannot handle further triggers from the CTP. This is either done directly or through the FANIN module to the LTU with a busy signal.

Due to dense cabling, four of the ALICE sub-detectors (TPC, PHOS, FMD and EMCal), utilize a BusyBox to keep track of free buffers in their Fec. The BusyBox asserts the busy signal to the LTU when one or more of these conditions are true:
# Buffers in Fec are full
# Upon receiving a trigger sequence from TTC
# When the TTC sends a global reset to the Fee

The busy signal is de-asserted when one or more FEC buffers are freed

The BusyBoxes are located in the DAQ counting rom.

== Overview ==

Traditionally the Fee in ALICE sub-detectors indicates when its buffers are full and cannot handle further triggers from the CTP. This is either done directly or through the FANIN module to the LTU with a busy signal.

Due to dense cabling, four of the ALICE sub-detectors (TPC, PHOS, FMD and EMCal), utilize a BusyBox to keep track of free buffers in their Fec. The BusyBox asserts the busy signal to the LTU when one or more of these conditions are true:
# Buffers in Fec are full
# Upon receiving a trigger sequence from TTC
# When the TTC sends a global reset to the Fee

The busy signal is de-asserted when one or more FEC buffers are freed

The BusyBoxes are located in the DAQ counting rom.

== Overview ==

Traditionally the Fee in ALICE sub-detectors indicates when its buffers are full and cannot handle further triggers from the CTP. This is either done directly or through the FANIN module to the LTU with a busy signal.

Due to dense cabling, four of the ALICE sub-detectors (TPC, PHOS, FMD and EMCal), utilize a BusyBox to keep track of free buffers in their Fec. The BusyBox asserts the busy signal to the LTU when one or more of these conditions are true:
# Buffers in Fec are full
# Upon receiving a trigger sequence from TTC
# When the TTC sends a global reset to the Fee

The busy signal is de-asserted when one or more FEC buffers are freed

The BusyBoxes are located in the DAQ counting rom.

== Overview ==

Traditionally the Fee in ALICE sub-detectors indicates when its buffers are full and cannot handle further triggers from the CTP. This is either done directly or through the FANIN module to the LTU with a busy signal.

Due to dense cabling, four of the ALICE sub-detectors (TPC, PHOS, FMD and EMCal), utilize a BusyBox to keep track of free buffers in their Fec. The BusyBox asserts the busy signal to the LTU when one or more of these conditions are true:
# Buffers in Fec are full
# Upon receiving a trigger sequence from TTC
# When the TTC sends a global reset to the Fee

The busy signal is de-asserted when one or more FEC buffers are freed

The BusyBoxes are located in the DAQ counting rom.
