| AXI LDPC Encoder block diagram |
Data frame is fed to the frame data (s_tdata) and DVB parameters should be
synchronized with it.
Values from the DVB tables (Annexes B and C from ETSI EN 302 307-1 V1.4.1), are
expanded to per bit and fed to the s_ldpc interface. This interface need 2
values: the actual frame offsets (s_ldpc_offset) and when to process another
frame bit (s_ldpc_next).
When s_ldpc_tlast is received, accumulation is considered completed and the
final accumulation begins, in which point the component will not accept any data
until the output frame is fully written.
