The increasingly demanding requirements of digital signal processing applications like multimedia, new generations of wireless systems, etc. led to the definition of more and more complex algorithms and systems that are to be efficiently implemented with the time to market constraint. Today, the electronic system design community is mainly concerned with defining efficient System-on-a-Chip (SoC) design...
In Software Defined Radio (SDR), some or all of the physical layer functions are implemented by software. In this paper, we focus on the channel decoding part of SDR. We use Synchronous Data Flow (SDF) and Cyclo-Static Data Flow (CSDF) graphs to model channel decoding functions. We want to tackle the problem of scheduling a dynamic mix of multiple radios with throughput constraints on a multi-standard...
The efficient implementation of high-rate high-throughout low-density parity-check (LDPC) code decoding presents challenges to both fully parallel decoding and memory-sharing partially parallel decoding schemes. In this paper, a new decoding scheme, sliced message passing (SMP), is introduced. The key idea is to slice the total set of N variable-to-check messages into equal-sized p chunks, then to...
