Toshiba Memory Corporation Develops High-Speed and High-Energy-Efficiency Algorithm and Hardware Architecture for Deep Learning Processor
Toshiba Memory Corporation, the world leader in memory solutions, today announced the development of a high-speed and high-energy-efficiency algorithm and hardware architecture for deep learning processing with less degradations of recognition accuracy. The new processor for deep learning implemented on an FPGA  achieves 4 times energy efficiency compared to conventional ones. The advance was announced at IEEE Asian Solid-State Circuits Conference 2018 (A-SSCC 2018) in Taiwan on November 6.
Deep learning calculations generally require large amounts of multiply-accumulate (MAC) operations, and it has resulted in issues of long calculation time and large energy consumption. Although techniques reducing the number of bits to represent parameters (bit precision) have been proposed to reduce the total calculation amount, one of proposed algorithm reduces the bit precision down to one or two bit, those techniques cause degraded recognition accuracy. Toshiba Memory developed the new algorithm reducing MAC operations by optimizing the bit precision of MAC operations for individual filters  in each layer of a neural network. By using the new algorithm, the MAC operations can be reduced with less degradation of recognition accuracy.
Furthermore, Toshiba Memory developed a new hardware architecture, called bit-parallel method, which is suitable for MAC operations with different bit precision. This method divides each various bit precision into a bit one by one and can execute 1-bit operation in numerous MAC units in parallel. It significantly improves utilization efficiency of the MAC units in the processor compared to conventional MAC architectures that execute in series.
Toshiba Memory implemented ResNet50, a deep neural network, on an FPGA using the various bit precision and bit-parallel MAC architecture. In the case of image recognition for the image dataset of ImageNet, the above technique supports that both operation time and energy consumption for recognizing image data are reduced to 25 % with less recognition accuracy degradation, compared to conventional method.
Artificial intelligence (AI) is forecasted to be implemented in various devices. The developed high-speed and low-energy-consumption techniques for deep-learning processors are expected to be utilized for various edge devices like smartphones and HMDs and datacenters which require low energy consumption. High-performance processors like GPU are important devices for high-speed operation of AI. Memories and storages are also one of the most important devices for AI which inevitably use big data. Toshiba Memory Corporation is continuously focusing on research and development of AI technologies as well as innovating memories and storages to lead data-oriented computing.
 FPGA: Field Programmable Gate Array, an integrated circuit designed
to be configured by a customer or a designer after manufacturing.
 filter: Generally, there are many filters of up to several thousands in one layer of a neural network.
 ResNet50: One of deep neural network, generally used to benchmark deep-learning for image recognition.
 ImageNet: A large image database, generally used to benchmark image-recognition, the number of image data is over 14,000,000.
 HMD: Head Mounted Display

Elliott Statement on Proposal to Uniper21.3.2019 10:00:00 EET | Tiedote
Elliott Advisors (UK) Limited (“Elliott”) has written to the Management Board of Uniper SE (the “Company” or “Uniper”), to formally request the convocation of an Extraordinary General Meeting (“EGM”) with the express purpose of instructing management to prepare a lawful domination agreement with the Company’s largest shareholder Fortum Oyj (“Fortum”). Elliott believes the thus far ill-defined and ambiguous nature of the relationship between Uniper and Fortum has created an unsatisfactory and unsustainable dynamic, which is detrimental to Uniper. In Elliott’s view, the status quo – operational underperformance and pervasive uncertainty – if sustained, will risk further undermining the Company’s fundamental value. Elliott believes a timely shareholder vote to advance a domination agreement may resolve the prolonged uncertainty at Uniper and clarify the relationship between the Company and Fortum, such that value can be created for the Company and all stakeholders. Elliott believes that F
Key UK SEP Patent Win for TQ Delta20.3.2019 22:03:00 EET | Tiedote
TQ Delta LLC, a technology development and licensing firm, secured a judgment on March 18 by the High Court of Justice of England and Wales immediately enjoining ZyXEL Communications UK Ltd and its Danish parent company, ZyXEL Communications A/S, from further infringement of TQ Delta's European Patent (UK) 1 453 268. TQ Delta's patent relates to Digital Subscriber Line ("DSL") technology. In an earlier judgment, handed down on March 12, the Court found that the patent was valid and essential to the operation of ADSL2 and VDSL2. In that judgment, the Court held that the ZyXEL defendants have infringed and continue to infringe the patent. The Court also found that a second patent would have also been essential and infringed but was invalid. In its judgment earlier this week, the Court also found that the ZyXEL defendants were "holding out" against taking a licence to TQ Delta's portfolio of patents relating to DSL. It granted an immediate injunction and costs against the ZyXEL defendants
