In recent years, Coarse Grain Reconfigurable Architecture (CGRA) accelerators have been increasingly deployed in Internet-of-Things (IoT) end nodes. A modern CGRA has to support and efficiently accelerate both integer and floating-point (FP) operations. In this paper, we propose an ultra-low-power tunableprecision CGRA architectural template, called TRANSprecision floating-point Programmable archItectuRE (TRANSPIRE), and its associated compilation flow supporting both integer and FP operations. TRANSPIRE employs transprecision computing and multiple Single Instruction Multiple Data (SIMD) to accelerate FP operations while boosting energy efficiency as well. Experimental results show that TRANSPIRE achieves a maximum of 10.06× performance gain and consumes 12.91× less energy w.r.t. a RISC-V based CPU with an enhanced ISA supporting SIMD-style vectorization and FP data-types, while executing applications for near-sensor computing and embedded machine learning, with an area overhead of 1.25× only.
This paper presents the design of signal simulator for advanced modern radar technology through field programmable gate array implementation. When considering all other possibilities, implementation of FPGA shows an impressive result in efficiency. By generating the complex waveform, chirp signal is sent to the destination by means of wide band spread spectrum. This approach is developed for an effective receiver end through filtering by using noise shaping, digital signal synthesizer and pulse accumulator. This system supports effective signal interference and jamming, and overcomes the inconvenience occur in its application.
