Some AMD Zynq™ UltraScale+™ RFSoCs include highly flexible Soft-Decision Forward Error Correction (SD-FEC) blocks for decoding and encoding data as a means to control errors in data transmission over unreliable or noisy communication channels. The SD-FEC blocks support low-density parity check (LDPC) decode/encode and Turbo decode for use in 5G wireless, backhaul, DOCSIS, and LTE applications.

You can use a total of eight cores for error as shown in the table of the SD-FEC page.

Figure 1. SD-FEC Table

Use the following inputs to estimate the power:

Mode
The following SD-FEC configuration modes are available for selection:
  • LDPC Encode
  • LDPC Decode
  • Turbo Decode
Standard
Specify the standard used for a particular application. You can select any of the following standards:
  • 5G
  • DOCSIS
  • Wi-Fi
  • Custom
  • LTE for Turbo Decode
Throughput Utilization
Specify the throughput utilization of the SD-FEC cores used. This is instance throughput relative to maximum throughput supported by the core.
Clock
Specify the clock for the SD-FEC core. After providing necessary inputs, PDM displays the estimated power for the VCCINT and VCCSDFEC power supplies.
