“…The Radio Frequency (RF) section that receives and sends the signal to the medium is essentially composed of the antenna and radio frequency amplifiers; the Intermediate Frequency (IF) section is responsible for changing the domain to the signal, i.e., in the case of a receiver, the signal goes from the analogue to the digital domain, while the operating frequency is taken to an intermediate frequency by means of the Digital Down-Converter (DDC); finally, the baseband section is where the signal is processed to demodulate and decode, and thus extract the information [7,8]. [8,9].…”

As multi-standard devices and high speed communication standards are emerging, timeliness requirements and flexibility for both baseband modem and medium access schemes are becoming essential. Software Defined Radios (SDRs), in this context, aim at offering the desired flexibility while satisfying the real-time constraints. An SDR architecture consisting of many-core homogeneous computing elements provides easy protocol implementation, a high level of portability and extension possibilities. It does not require architecture specific program code which is needed by the popular heterogeneous SDR architectures. Therefore, in this paper, we explore how a homogeneous SDR architecture is used for efficient realization and execution of Medium Access Control (MAC) protocols. In particular, we investigate the performance of two broad classes of MAC schemes on the Platform 2012 (P2012) many-core programmable computing fabric. We provide a toolchain which utilizes the characteristics of P2012 for MAC parallelization, runtime scheduling, and execution. Our results indicate that by using the supporting toolchain, reconfigurable MAC implementations are able to exploit the computational power offered by the platform and adhere to the timeliness constraints. Computationally intensive algorithms for MAC layer parameter optimization show an improvement of up to 85% in the convergence time as compared to using a single-core architecture.

The field-programmable gate array (FPGA) technology is expected to play a key role in the development of software-defined radio (SDR) platforms. As this technology evolves, low-level designing methods for prototyping FPGA-based applications did not change throughout the decades. In the outstanding context of SDR, it is important to rapidly implement new waveforms to fulfill such a stringent flexibility paradigm. At the current time, different proposals have defined, through software-based approaches, some efficient methods to prototype SDR waveforms in a processor-based running environment. This paper describes a novel design flow for FPGA-based SDR applications. This flow relies upon high-level synthesis (HLS) principles and leverages the nascent HLS tools. Its entry point is a domain-specific language (DSL) which handles the complexity of programming an FPGA and integrates some SDR features so as to enable automatic waveform control generation from a data frame model. Two waveforms (IEEE 802.15.4 and IEEE 802.11a) have been designed and explored via this new methodology, and the results are highlighted in this paper.
