SocLib Components General Index


1) Functional Description

This TC1700 is a flexible turbo decoder covering WiMAX, LTE and HSPA+ specifications provided by TurboConcept. Full documentation is available online at TurboConcept's Web Site.

TurboConcept's TC1700 Core is a turbo decoder that supports three PHY layer specifications:

  • 3GPP-LTE
  • WiMAX IEEE802.16e

The Core is optimized for ASIC and FPGA target and uses a unique architecture that reduces by more than 50 % the silicon area when compared to separate single-mode Cores, with no restrictions on the flexibility and features set.

Figure 1 - Tc1700

Figure 1 presents the general core structure. The Tc1700 is connected to a MWMR wrapper in order to interface the core to the MWMR controller available at VciMwmrController.

  • std::vector<tlm_utils::simple_target_socket_tagged<Tc1700,32,tlm::tlm_base_protocol_types> *> p_status: status port
  • std::vector<tlm_utils::simple_initiator_socket_tagged<Tc1700,32,tlm::tlm_base_protocol_types> *> p_read_fifo: port from the MWMR controller to the Tc1700
  • std::vector<tlm_utils::simple_initiator_socket_tagged<Tc1700,32,tlm::tlm_base_protocol_types> *> p_write_fifo: port from the Tc1700 to the MWMR controller

4) Limitation

This model has the following limitations:

  • fixed number of performed iterations.

The number of performed iterations is fixed to a reasonable value still offering close-to-ideal Bit Error Rate (BER) performances. Please contact TurboConcept for information about these limitations.

5) License

The MWMR wrapper is licensed under the SoCLib, GNU LGPLv2.1 license.

The MWMR wrapper instantiates an internal hardware decoder. This internal hardware decoder is licensed under BSD-like license.

This internal hardware decoder is distributed in a binary form.

6) RTL model

Please contact TurboConcept for information about purchasing a fully functional RTL model of the internal hardware decoder.
