Detailed Description

Transfer calorimeter data from Circular DPRAM to de-randomisation FIFO.

This module controls the transfer of calorimeter data from Circular DPRAM to the de-randomisation FIFO.

This FSM is responsible for transfering the correct RAW data associated with the required BCN.

The control signals ensure all 49 DPRAMs are read and written to 49 FIFOs in parallel.

The write address offset for SPRAM ensures the data associated with required BCN is read out.

When the prog_FULL flag of de-randomisation FIFO is set to 1, no more data is written to this FIFO
