Figure 3. Turbo Decoder Data Flow
Asynchronous reset initializes the core.
Block size and number of iterations is specified.
Data and parity values are placed on input bus
din and are written to input buffer.
MAP Decoder begins operating on the data block.
Computation of LLR for each data symbol begins.
After the iterations are computed, the results of
final LLR values are available in LLR memory.
The rfo pin is asserted so the user can
read the hard decision using handshake signal.
Hard decision is available on output pin dout .
Figure 4 shows the loading of block size and iterations for the current input block with assertion of input signal
blocksizeset(ipcfgset) after asynchronous reset rstn has been de-asserted. After the reset assertion, the
Turbo Decoder asserts rfi to indicate that it can receive a data block. At the same time the decoder de-asserts
rfo signal to show that there is no data available to give any hard decisions at the output.
