ML ASSISTED DYNAMIC DECODING GEAR SELECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18359147 titled 'ML ASSISTED DYNAMIC DECODING GEAR SELECTION

The abstract describes a multi-gear ECC decoder that switches between a high power decoder and a low power decoder to reduce decoding time for high-BER codewords.

The decoder includes a slow high power decoder and a fast low power decoder.
A controller determines whether to start decoding in slow high power or fast low power based on a predetermined factor.
The decoding process transitions between the two power levels during decoding.
Decoding continues in the second power level until completion or if another switch is needed.

Potential Applications: - Error correction in communication systems - Data storage systems - Wireless networks

Problems Solved: - Reducing decoding time for high-BER codewords - Efficient use of power resources - Improving overall system performance

Benefits: - Faster decoding of high-BER codewords - Optimal power utilization - Enhanced system reliability

Commercial Applications: Title: "Efficient ECC Decoder for High-BER Codewords" This technology can be applied in telecommunications, data centers, and IoT devices to improve data transmission efficiency and reliability.

Questions about the technology: 1. How does the controller determine the appropriate power level for decoding? - The controller uses a predetermined factor to decide whether to start decoding in slow high power or fast low power. 2. What are the advantages of switching between power levels during the decoding process? - Switching between power levels allows for efficient use of resources and faster decoding of high-BER codewords.

Original Abstract Submitted

A multi-gear ECC decoder includes a high power decoder and a low power decoder. In order to significantly reduce the decoding time for high-BER codewords using a slow high power decoder, rather than decoding codewords in either slow high power or fast low power, a controller switches between slow high power decoding and fast low power decoding during the decoding process. The controller first will determine, based on a predetermined factor, whether to start decoding in slow high power or fast low power. Once a decoding power is determined, then the decoding will begin. During the decoding process the decoding transitions from a first power lever decoder to a second power level decoder. The decoding will continue in the second decoding power level after the transition, until the decoding is completed or if another switch needs to occur for insufficient decoding.
