Abstract
A polar decoder circuit can execute successive cancellation list polar decoding on multiple threads concurrently. An LLR update engine of the polar decoder circuit and a sort engine of the polar decoder circuit can operate concurrently, with the LLR update engine computing updated path metrics for one codeword while the sort engine sorts candidates for one or more other codewords according to path metrics already computed by the LLR update engine. Threads corresponding to different codewords can cycle sequentially between the LLR update engine and the sort engine.
