Hi TI,

      I like to know whats the difference between the encoder which is present in BCP and TCP3e Accelerator in C6670 processor. why two encoders are implanted in the SOC and whats the reason behind it.

    Hi TI Team,

                    I want to know whether the Encoder Module in BCP and TCP3e are same .  If same how the communication between BCP and TCP3e takes place.

    Hi Janeeth, Saravanan,

    The BCP ENC sub-module supports both convolutional and turbo encoding and is provided in the BCP to support efficient downlink physical layer processing. BCP accelerates Layer 1 downlink processing from transport blocks down to OFDM symbols (LTE/WiMAX) or physical channel data (WCDMA/TD-SCDMA, HSPA/+), and as such the on-chip TCP3E is not needed when using BCP (You can still use the TCP3E for other tasks as per your application needs).

    In fact, future generations of our devices that include the BCP may not have seperate TCP3Es.
