Tools and approaches to efficiently implement Deep Learning in embedded systems

Presenter:
Dr. Marc Duranton, CEA (French Atomic Energy Commission)

Marc Duranton Marc Duranton

Abstract: Artificial Intelligence, and more particularly Deep Learning are enablers of new applications, and allow computing systems to better interact with the real world by extracting information from signals, images and sounds. But they are demanding in computing power and therefore energy, and pose challenges for being used in embedded systems. This presentation will present some uses cases, tools, approaches and hardware allowing to select neural networks and hardware implementations tuned for embedded applications (Deep Learning at the edge). It will also include some highlight on Auto-ML and on computations using “spiking” data representation.”

Spiking Neural Networks for Artificial Vision. From Sensing, to Processing and Learning

Presenter:
Dr. B. Linares-Barranco, Scientist , Instituto de Microelectronica de Sevilla

B. Linares-Barranco B. Linares-Barranco

Abstract: The brain processes information in a very efficient manner by using some kind of spike encoding technique, despite the fact that the underlying technology (neurons) is slow, faulty, and noisy. Since decades neuromorphic engineering has attempted to imitate the sensing and processing of biological neural systems with the hope to develop artificial systems capable of approaching the brain capabilities. We will present CMOS spiking vision sensors and spiking based processing techniques that allow for extremely fast recognition capabilities. Additionally, emerging memory technologies (such as RRAM) have the potential to be exploited for implementing self-learning and/or highly compact spike processing systems. We will review show some techniques for implementing such capabilities.

Developments and Practices for Testing MRAM Memories

Presenter:
Patrick Girard, LIRMM - CNRS / France

Patrick Girard Patrick Girard

Abstract: Memories occupy most of the silicon area in nowadays System-on-Chips. Though widely used, non-volatile Flash memories still have several drawbacks. MRAMs have the potential to mitigate almost all Flash related issues. However, they are prone to defects as any other kind of memories. This embedded tutorial provides an up-to-date and practical coverage of MRAM testing. The first part gives some background on Magnetic Tunnel Junction and existing MRAM technologies. Then, an MRAM architecture used to illustrate the development of test and reliability solutions is presented. The next part detailed resistive-open, resistive-bridge and capacitive defect injection campaigns that are usually performed in order to analyze specific failure mechanisms of MRAMs. Specific functional fault models associated to these failure mechanisms are then described. The last part of the tutorial presents March test algorithms developed for MRAM testing and their validation in industrial environments.

High Energy Efficient Reconfigurable Neural Network Processor Design

Presenter:
Dr. Shouyi Yin, Professor/Vice Director , Institute of Microelectronics Tsinghua University

Dr. Shouyi Yin Dr. Shouyi Yin

Abstract: With the rapid development of information technology, the emerging applications, especially artificial intelligence (AI), bring severe challenges to both energy efficiency (the ratio of performance to energy consumption) and flexibility of computing chips. The traditional computing chips with software programming (such as CPU) or hardware programming (such as FPGA) are difficult to meet the requirements of high energy efficiency. Application Specific Integrated Circuit (ASIC) has high energy efficiency, but the poor flexibility restricts its application under the pressure of high cost of <10nm process technology. Coarse-grained reconfigurable computing is a promising solution which combines high energy-efficiency of hardwired logics and high flexibility of software programming. In the reconfigurable architecture, computing units, storage units and interconnection resources compose a regular parallel and distributed processing element (PE) array, which is dynamic reconfigurable. The software applications (programmed by high-level language, such as C) are synthesized into configuration context for reconfiguring hardware resources at run time. In this tutorial, a survey of basic ideas and recent techniques of coarse-grained reconfigurable architecture (CGRA) is presented. A preliminary analysis of the current challenges and future trends of AI processors are introduced to understand the system constraints, and translate them into design specifications. Then several practical reconfigurable processors are presented to demonstrate the potential and benefits of CGRA. As particularly important case, low-power neural networks processors are discussed by highlighting the “reconfigurability” that are enabling the recent and very rapid improvements in energy efficiency.
