Abstract :
In this paper we propose an efficient and generic HDL library of processing units which are the key elements of a modular low-density parity check (LDPC) decoder design approach. General purpose, low complexity and high throughput bit node and check functional models are developed. Both full serial and parallel architectures are considered. Also, it is described an automatic HDL code generator for the proposed processing units using Matlab language and synthesis results for a Xilinx FPGA device are documented
