Systems and techniques for forward error correction decode processing power reduction are described herein. A capacity of a network slice is determined for a user network interface (UNI) based on a subset of forward error correction (FEC) codewords to be decoded by the media access control processor. A number of decoder cores is calculated to decode the capacity of the network slice. A utilization value is determined for a decoder core. A decoder utilization value is calculated for the decoder cores using the utilization value a number of decoding iterations. A non-decoding media access control processor utilization value is obtained for the network slice. A geometry is calculated for the media access control processor using the number of decoder cores, the decoder utilization value, and the non-decoding media access control processor utilization value. A media access control processor manufacturing specification data is generated based on the calculated geometry.

Reduced power media access control processor design

Systems and techniques for forward error correction decode processing power reduction are described herein. A first codeword is identified in a network transmission. A conditional decoding window is generated that begins with the first codeword. The conditional decoding window is aligned with a frame of the network transmission. A report is generated that includes an indication of relevance of the conditional decoding window to a network device. The conditional decoding window and the report are transmitted to the network device. A conditional decoding window is received that includes a first codeword. The first codeword is decoded to determine a second codeword. A report is obtained that includes a codeword relevance bit for the second codeword. Upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, the second codeword is discarded without decoding the second codeword.
