摘要: Low-density parity-check (LDPC) block codes are popular forward error correction schemes due to their capacity-approaching characteristics. However, the realization of LDPC decoders that meet both low latency and high throughput is not a trivial challenge. Usually, this has been solved with the ASIC and FPGA technology that enables meeting the decoder design constraints. But the rise of parallel architectures, such as graphics processing units, and the scaling of CPU streaming extensions has shown that multicore and many-core technology can provide a flexible alternative to the development of dedicated LDPC decoders for the compute-intensive prototyping phase of the design of new codes. Under this light, this paper surveys the most relevant publications made in the past decade to programmable LDPC decoders. It looks at the advantages and disadvantages of parallel architectures and data-parallel programming models, and assesses how the design space exploration is pursued regarding key characteristics of the underlying code and decoding algorithm features. This paper concludes with a set of open problems in the field of communication systems on parallel programmable and reconfigurable architectures.

摘要: A coarse-grained reconfigurable processing unit (RPU) consisting of multi-functional processing elements (PEs) interconnected by an area-efficient line-switched mesh connect (LSMC) routing is implemented on a die in TSMC 65 nm LP1P8M CMOS technology. A hierarchical configuration context (HCC) organization scheme is proposed to reduce the implementation overhead and the energy dissipation spent on fast reconfiguration. The proposed RPU is integrated into two system-on-a-chips (SoCs), targeting multiple-standard video decoding. The high-performance chip, comprising two RPU processors (named REMUS_HPP), can decode H.264 video streams at 30 frames per second (fps) under 200 MHz. REMUS_HPP achieves a 25% performance gain over the XPP-III reconfigurable processor with only 280 mW power consumption, resulting in a improvement on energy efficiency. The other chip (named REMUS_LPP), targeting low power applications, integrates only one RPU processor. REMUS_LPP can decode H.264 video streams at 35fps with 24.5 mW under 75 MHz, achieving a 76% reduction in power dissipation and improvement on energy efficiency compared with the ADRES reconfigurable processor.

摘要: Software-defined radio (SDR) allows the unprecedented levels of flexibility by transitioning the radio communication system from a rigid hardware platform to a more user-controlled software paradigm. However, it can still be time-consuming to design and implement such SDRs as they typically require thorough knowledge of the operating environment and a careful tuning of the program. In this paper, our contribution is the design of a bidirectional transceiver that runs on the commonly used USRP platform and implemented in MATLAB using standard tools like MATLAB Coder and MEX to speed up the processing steps. We outline strategies on how to create a state-action-based design, wherein the same node switches between transmitter and receiver functions. Our design allows the optimal selection of the parameters toward meeting the timing requirements set forth by various processing blocks associated with a differential binary phase shift keying physical layer and CSMA/CA/ACK MAC layer, so that all the operations remain functionally compliant with the IEEE 802.11b standard for the 1 Mb/s specification. The code base of the system is enabled through the Communications System Toolbox and incorporates channel sensing and exponential random back-off for contention resolution. The current work provides an experimental testbed that enables the creation of new MAC protocols starting from the fundamental IEEE 802.11b standard. Our design approach guarantees consistent performance of the bi-directional link, and the three-node experimental results demonstrate the robustness of the system in mitigating packet collisions and enforcing fairness among nodes, making it a feasible framework in higher layer protocol design.

摘要: Reconfigurable architectures can bring unique capabilities to computational tasks. They offer the performance and energy efficiency of hardware with the flexibility of software. In some domains, they are the only way to achieve the required, real-time performance without fabricating custom integrated circuits. Their functionality can be upgraded and repaired during their operational lifecycle and specialized to the particular instance of a task. We survey the field of reconfigurable computing, providing a guide to the body-of-knowledge accumulated in architecture, compute models, tools, run-time reconfiguration, and applications.
