  The near channel performance of Low Density Parity Check Codes (LDPC) has
motivated its wide applications. Iterative decoding of LDPC codes provides
significant implementation challenges as the complexity grows with the code
size. Recent trends in integrating Multiprocessor System on Chip (MPSoC) with
Network on Chip (NoC) gives a modular platform for parallel implementation.
This paper presents an implementation platform for decoding LDPC codes based on
HeMPS, an open source MPSoC framework based on NoC communication fabric.
Reduced minimum sum algorithm is used for decoding LDPC codes and simulations
are performed using HeMPS tool. The data rate and speedup factor measured for
decoding a rate 1/2 LDPC code characterised by 252x504 parity matrix is
presented
