A turbo decoder includes a plurality of decoder cores arranged for parallel decoding of a plurality of code segments of a code block in an iteration. Each of the decoder cores is arranged to decode a corresponding code segment according to a sliding window having a window size smaller than a length of the corresponding code segment in most cases, and sequentially generate a plurality of decoded soft outputs each derived from decoding an encoded soft input selected from the corresponding code segment by the sliding window.

Adaptive multi-core, multi-direction turbo decoder and related decoding method thereof

A decoding apparatus has an on-chip buffer, an external buffer interface, and a turbo decoder. The on-chip buffer is arranged for buffering each code block to be decoded. The external buffer interface is arranged for accessing an off-chip buffer. The turbo decoder is arranged for decoding a specific code block read from the on-chip buffer. The specific code block is not transmitted from the on-chip buffer to the off-chip buffer via the external buffer interface unless decoding fail of the specific code block is identified.
