Example 11-3. Master Transfer Execution

-- 10 x packet at transfer level with

-- Number of transfer = i % 10. Values : 1, 2 .. 10

-- id = i % 15. Values 0, 1, 2 .. 14

-- dest = i %20. Values 0, 1, 2 .. 19

for i in 0 to 9 loop

transfer_count := (i mod 10) + 1;

create_master_transaction(transfer_count, trans, index,

axi4stream_tr_if_0(index));

set_id(i mod 15, trans, index, axi4stream_tr_if_0(index));

set_dest(i mod 20, trans, index, axi4stream_tr_if_0(index));

m := 0;

while(m < transfer_count) loop

k := m;

while(k < transfer_count) loop

set_data(k, k, trans, index, axi4stream_tr_if_0(index));

if(((i + m) mod 5) = 0) then

set_byte_type(AXI4STREAM_NULL_BYTE, m, trans, index,

axi4stream_tr_if_0(index));

elsif(((i + m) mod 5) = 1) then

set_byte_type(AXI4STREAM_POS_BYTE, m, trans, index,

axi4stream_tr_if_0(index));

else

set_byte_type(AXI4STREAM_DATA_BYTE, m, trans, index,

axi4stream_tr_if_0(index));

end if;

k := k + 1;

end loop;

execute_transfer(trans, m / byte_count, index,

axi4stream_tr_if_0(index));

m := m + byte_count;

end loop;
