A scalable ASIP for BP Polar decoding with multiple code lengths

Polar Code Construction for List Decoding

A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in frame error rate (FER) and decoding complexity. Furthermore, a construction based on dynamically frozen bits with constraints among the ”low weight bits” (LWB) is presented. Simulation results show that the LWB-polar ...

A Scalable Multi-Core ASIP Virtual Platform For Standard-Compliant Trellis Decoding

Multi standard wireless modems are becoming more and more important in industry. The recent move to LTE will aggravate this issue. We present a scalable Multi-Core ASIP virtual platform for trellis based channel decoding in multi-standard wireless modems. The basic building block of the platform is a weakly programmable IP-Core which was designed with the Processor Designer from Synopsys. This ...

Simulation Analysis of Multiple BP Decoding Algorithm and FFT-BP Decoding Algorithm

In order to solve the problem that the original decoding algorithm of multi-band LDPC codes is high and is not conducive to hardware implementation, two simplified decoding algorithms for multi-band LDPC codes are studied: the reliability propagation based on fast Fourier transform Code algorithm (FFT-BP) and log-BP decoding algorithm based on logarithmic operations. The simulation results show...

Polar code design and decoding for magnetic recording

Fixed-point arithmetic for ASIP code generation

In this paper we present an environment supporting fixed-point arithmetic in C programs. It allows the specification of the position of the binary point in the source code and code generation for architectures with hardware support for the fixed-point arithmetic. Our tools are implemented on the top of the SUIF C compiler[1] and do not require any special adaptations. We demonstrate the validit...
