4.2. 4G Turbo-V Uplink Accelerator

The uplink accelerator comprises a subblock deinterleaver and a turbo decoder (Intel Turbo FPGA IP)
Figure 7. 4G Channel Uplink Accelerator

The deinterleaver consists of three blocks in which the first two blocks are symmetrical and the third block is different.

Figure 8. Deinterleaver

If you turn on the bypass mode for the subblock deinterleaver, the IP reads the data as it writes the data in the memory blocks in the successive locations. The IP reads the data as and when it writes the data without any interleaving. The number of input data into the subblock deinterleaver is K_π in the bypass mode and the output data length is k size (k is the code block size based on the cb_size_index value).
