Non-Binary LDPC Encoder Circuit Using Multi-Stage Vector Processing

The patent divides the non-binary encoding process into multiple stages, where each stage handles a portion of the encoding operation. The encoder circuit processes input data through sequential stages, with each stage performing specific vector operations. This segmentation allows the complex non-binary encoding to be broken down into manageable circuit blocks, reducing overall circuit complexity while maintaining decoding performance benefits.

The patent introduces intermediate vectors as mediators in the encoding process. Instead of directly implementing complex non-binary encoding, the system uses intermediate vectors to bridge the input data and final codeword. These intermediate vectors serve as temporary storage and transformation carriers, allowing the circuit to process non-binary data through a series of simpler vector operations rather than requiring a single complex operation.

The patent designs the encoder circuit to perform multiple functions using the same hardware resources. The circuit can operate in different encoding modes and handle various data types through configurable parameters. This multi-functionality allows the same circuitry to serve multiple purposes, reducing the total amount of hardware needed while maintaining high decoding performance across different operational scenarios.

The patent employs parameter changes to adapt the circuit operation without requiring physical reconfiguration. By changing operational parameters such as vector dimensions, matrix properties, and processing stages, the same circuit hardware can achieve different decoding performance levels. This allows performance optimization through software-controlled parameter adjustment rather than hardware modification.
