Request processing by the LRI2K
Upon reception of a valid request, the LRI2K performs the following algorithm:
●
●
●
●
●
●
SN = 0
if (Nb_slots_flag)
label1:
if LSB(UID, SN_length + Mask_length) =
wait (Slot_Frame)
if Slot_Frame = SOF
if Slot_Frame = EOF
LSB(SN,SN_length)&LSB(Mask,Mask_length)
then NbS = 1
else NbS = 16
then answer to inventory request
then Stop Anticollision
if SN < NbS-1
endif
NbS is the total number of slots (1 or 16)
SN is the current slot number (0 to 15)
LSB (value, n) function returns the n Less Significant Bits of value
MSB (value, n) function returns the n Most Significant Bits of value
"&" is the concatenation operator
Slot_Frame is either an SOF or an EOF
then SN = SN + 1
SN_length = 0
endif
SN_length = 4
endif
endif
decode/process request
exit
endif
goto label1
exit
endif
