PrefixGPT: Prefix Adder Optimization by a Generative Pre-trained Transformer

AAAI 2026technical

Prefix adders are widely used in compute-intensive applications for their high speed. However, designing optimized prefix adders is challenging due to strict design rules and an exponentially large design space. We introduce PrefixGPT, a generative pre-trained Transformer (GPT) that directly generat

Approximate Belief Propagation Decoder for Polar Codes

ICASSP 2018accepted

Polar code is increasing its popularity recently for its capacity-achieving property for B-DMCs. However, when designing decoders for polar code, it has always been an inevitable concern for us to balance the decoding performance and the hardware consumption. In this paper, we propose an approximate…

Accelerating stochastic computation for binary classification applications

ICASSP 2016accepted

Stochastic computation is a non-conventional computation paradigm, which uses digital circuits to operate on stochastic bit streams. Although it has advantages such as strong fault tolerance and low hardware cost, its drawback is its long computation time. In this work, we target at stochastic compu…
