13. FPGA Implementation of Non-Linear Predictors.

Abstract

The paper describes the implementation of a systolic array for a non-linear predictor for image and video compression. We use a multilayer perceptron with a hardware-friendly learning algorithm. Until now, mask ASICs (full and semicustom) offered the preferred method for obtaining large, fast, and complete neural networks for designers who implement neural networks. Now, we can implement very large interconnection layers by using large Xilinx and Altera devices with embedded memories and multipliers alongside the projection used in the systolic architecture. These physical and architectural features — together with the combination of FPGA reconfiguration properties and a design flow based on generic VHDL — create a reusable, flexible, and fast method of designing a complete ANN on FPGAs. Our predictors with training on the fly, are completely achievable on a single FPGA. This implementation works, both in recall and learning modes, with a throughput of 50 MHz in XC2V6000-BF957-6 of XILINX, reaching the necessary speed for real-time training in video applications and enabling more typical applications to be added to the image compression processing [ABSTRACT FROM AUTHOR]

Abstract

WOS: 000372866900001, The NEutron Detector Array (NEDA) project aims at the construction of a new high-efficiency compact neutron detector array to be coupled with large gamma-ray arrays such as AGATA. The application of NEDA ranges from its use as selective neutron multiplicity filter for fusion-evaporation reaction to a large solid angle neutron tagging device. In the present work, possible configurations for the NEDA coupled with the Neutron Wall for the early implementation with AGATA has been simulated, using Monte Carlo techniques, in order to evaluate their performance figures. The goal of this early NEDA implementation is to improve, with respect to previous instruments, efficiency and capability to select multiplicity for fusion-evaporation reaction channels in which 1, 2 or 3 neutrons are emitted. Each NEDA detector unit has the shape of a regular hexagonal prism with a volume of about 3.23 l and it is filled with the EJ301 liquid scintillator, that presents good neutron-gamma discrimination properties. The simulations have been performed using a fusion-evaporation event generator that has been validated with a set of experimental data obtained in the Ni-58 + Fe-56 reaction measured with the Neutron Wall detector array., MINECO, Spain [FPA2011-29854-C04, FPA2012-33650, FPA2014-57196-C5]; Generalitat Valenciana, Spain [PROMETEO/2010/101, PROMETEOII/2014/019]; European Regional Development Fund (FEDER) of European Commission; Swedish Research Council; Polish National Science Centre [801/N-COPIN/2010/0, UM0-2014/14/M/ST2/00738, UM0-2013/08/M/ST2/0025]; Scientific and Technological Council of Turkey [106T055, 114F473]; UK STFC [ST/L005727/1]; Science and Technology Facilities Council [ST/L005727/1, ST/L005735/1], This work was partially supported by MINECO, Spain, under the grants FPA2011-29854-C04, FPA2012-33650 and FPA2014-57196-C5, and Generalitat Valenciana, Spain, under the grants PROMETEO/2010/101 and PROMETEOII/2014/019, The European Regional Development Fund (FEDER) of European Commission, the Swedish Research Council, the Polish National Science Centre under contracts: 801/N-COPIN/2010/0 (COPIN/IN2P3 collaboration), UM0-2014/14/M/ST2/00738 (COPIN-INFN collaboration), UM0-2013/08/M/ST2/0025 (LEA-COPIGAL collaboration), the Scientific and Technological Council of Turkey (Proj. no. 106T055 and 114F473), and the UK STFC (ST/L005727/1).
