Keynote
Keynote Address: IoT Standards Wars: Designers Caught in the Middle?
Linley Gwennap, Principal Analyst, The Linley Group
The Internet of Things is not a single market but rather a plethora of things, each with its own technology requirements and target customer. As a result, many new standards are being proposed, but these standards may meet the needs of only certain types of IoT devices. This presentation will discuss standards for communication protocols, software, and services for IoT devices, helping to sort out which are applicable and which are most likely to succeed. It will also address technologies for securing the IoT and other trends affecting SoC design.
Hardware Track
Addressing the Evolving Processing Needs of IoT Applications
Rich Collins, Product Marketing Manager, 草榴社区
As IoT device implementations mature, in addition to meeting the integration and low-power demands of battery operated IoT applications, designers are looking to address the increasing processing needs of these applications. Sensor fusion has evolved into the broader scope of data fusion, where voice recognition, audio playback, face detection and basic gesture recognition complement the sensor processing functions on an IoT device. Ensuring secure operation and transmission of data is also critical for IoT devices supporting fitness and health applications, financial transactions and e-government products. Efficient processors and pre-verified, SoC-ready subsystems simplify the development of chips targeting ever more complex IoT applications with dedicated features addressing the evolving security and processing needs of these new IoT devices.
To manage this onslaught of new functionality, IoT edge devices increasingly require higher bandwidth analysis to be performed locally (on-chip). 草榴社区 and Renesas have worked together to build a new reference design supporting power efficient data fusion processing with higher performance MONOS embedded flash technology to provide the ideal power/performance trade-offs required for the next generation of IoT devices.
APEX: Using ARC Processor Custom Extensions to Differentiate Your SoC
Joep Boonstra, Sr. Staff Architect, 草榴社区
In a highly competitive semiconductor market, it is increasingly important to be able to quickly and easily differentiate your device. This session will introduce ARC Processor EXtension (APEX) technology, which can be used to extend the instructions and register set of the CPU as well as add tightly coupled peripherals and custom interfaces to the core. It will also include real-world examples and recent additions to optimize performance for complex extensions while retaining a simplified interface.
IoT Security: Protecting Your SoC from Malicious Physical and Software Attacks
Ruud Derwig, Software and Systems Architect, 草榴社区
Security is of critical importance to IoT applications. This session will present threats to IoT security, and hardware-rooted processor security solutions that defend against these. Both logical (software) as well as physical (hardware) attacks will be addressed. Special attention will be given to countermeasures for Side Channel Analysis (SCA) attacks, or non-invasive physical attacks that reconstruct secret cryptography keys from information leaked from an SoC’s power consumption or electromagnetic radiation. Without countermeasures, it can be surprisingly easy to obtain these secret keys, and therefore SCA countermeasures are required by more and more IoT standards.
Maximizing Embedded Performance with Multicore Processors

Designing with Processors in Safety-Critical Automotive Applications
Fergus Casey, Senior R&D Manager, 草榴社区
As more SoC designs are used in electronic systems deployed in safety-critical applications, functional safety is an important consideration in system architecture and verification methodology. Security is also a key concern for connected cars and should be a consideration in safety applications. This session will outline the key requirements for ISO 26262 and security as they relate to processor IP and demonstrate how safety-critical IP and SoC developments can be greatly accelerated through the use of out-of-the-box safety ready IP, together with advanced verification qualification tools and methodologies.
Achieving 7X Better Power Efficiency with a Unique Sub-Threshold Technology Implementation of an ARC EM5D Processor Based Subsystem
Uzi Zangi, CEO & Co-founder, PLSense
The emerging Internet-Of-Things (IoT) market is causing the focus of IC design flows to shift from increasing performance to reducing power in order to meet the demands of battery operated devices to increase their battery lifetime. PLSense has developed comprehensive technology for sub-threshold libraries and design flows, which enables the design of ICs that can operate at voltages as low as 0.45V while significantly improving battery life compared to existing solutions. As part of this technology, PLSense implemented an MCU chip fabricated on the TSMC 40-nm ULP process using 草榴社区’ DesignWare? Smart Data Fusion IP Subsystem. This presentation will describe the implementation of the MCU using the sub-threshold technology and show how it achieved up to 7X better power per MHz than comparable solutions.
Designing a Next-Generation PCI Express-Based Enterprise SSD Solution using ARC Processors
Tao Wang, Chief Engineer, Digital Verification, Starblaze
High performance, small form factor and low power consumption are important considerations in the design and selection of an SSD product. Enterprise SSD products are also characterized by a very high “mean time between failures” (MTBF) value, high data integrity and end-to-end data protection. Enterprise SSD products are expected to be used in heavy workload environments and still deliver high performance. This presentation addresses the challenges and requirements for the underlying CPU in an Enterprise SSD solution. It highlights how a multi-core ARC HS Processor and ARC EM Processor based SoC proves to be the ideal choice for the Enterprise SSD product, and explains how ARC processors can easily meet key Enterprise SSD application requirements.
Software Track

Sensor Processing for Smart Home and IoT
Dave Karlin, VP of Strategy, Hillcrest Labs
Many emerging applications, such as virtual reality, augmented reality, and robotics have unique sensor processing requirements and require an optimum combination of hardware and software. This presentation will focus on how Hillcrest Labs’ specialized software and 草榴社区’ ARC processors can enable high-accuracy, low-power sensor processing for Smart Home and a wide range of IoT applications.
Using the MPU with an RTOS to Enhance System Safety and Security
Steve Ridley, Principal Software Engineer, WITTENSTEIN
For safety-critical software, it is necessary to understand the requirements of the application, be able to demonstrate that the requirements have been met and prove that all the code is necessary and tested. This disciplined approach to engineering is the starting point for safety applications. Run time monitoring of an application and its underlying hardware is also commonplace. One hardware peripheral that can help with this is a Memory Protection Unit (MPU). Correct configuration of the MPU can allow software bugs or corruption to be trapped before damage can occur; however, active management of the MPU in conjunction with an RTOS allows meaningful task/thread isolation of mission critical parts of the application. This presentation discusses methods of achieving partitioning and error detection using the MPU.
Software Development Kits for Simplifying Security Implementation
Mike Borza, Member of Technical Staff, Security IP, 草榴社区
Secure Boot can greatly enhance the security of an embedded system by verifying that the code being loaded and executed has not been unknowingly or maliciously modified. This presentation will cover the Secure Boot Software Development Kit, which allows developers to implement Secure Boot systems using software-only constructs or with 草榴社区 offload engines. It will also provide an overview of 草榴社区 cryptography software, which includes a comprehensive suite of widely used crypto algorithms and simple plug-in modules to transparently support hardware acceleration or offload.
A Lightweight Trusted Execution Environment for IoT Edge Devices
Ruud Derwig, Software and Systems Architect, 草榴社区
Developing completely bug-free software is complex and costly, but the bugs that remain pose a security threat when maliciously exploited. In addition, software in a device comes from sources with different trust levels: internal development, external suppliers, open source, and maybe even end-users. The standard solution for mixed-criticality components is isolation. For security this means a securely shielded Trusted Execution Environment. For low power/cost IoT edge devices, however, a separate secure processor or full virtualization is not an option. This session presents a lightweight solution to efficiently shield secure from non-secure software on a single microcontroller.
Pervasive Authentication for IoT: ARC Processors with PUFs
Pim Tuyls, CEO, Intrinsic-ID
This presentation will explain Physical Unclonable Functions (PUF) technology and how it can be used for authentication and encryption in IoT and embedded systems. Also, it will cover how PUF is integrated into the ARC architecture and how it interacts with other security features and crypto accelerators. The presentation includes an example using PUF to authenticate a sensor to the cloud and guidance for designers who need to find a balance between performance, code size, and gate count.
Embedded Natural Language Voice Interfaces
Kashif Kahn, CEO, Sage Senses
Advances in machine learning and embedded engineering technologies now make it possible to design and implement sophisticated natural language voice interfaces on ordinary microcontrollers. Embedded voice interfaces address connectivity, bandwidth, latency, energy, and/or privacy issues associated with cloud-based speech systems. They can be utilized either as a complement (eg. backup) or as an alternative to cloud-based speech systems. For most “command-and-control” applications in consumer and industrial domains, a natural language voice interface can be deployed on a microcontroller with less than 1 MB of RAM+ROM and 200 MHz CPU. Further, a developer can train a sophisticated Natural Language Understanding (NLU) engine for his voice interface with a small amount of data.
The Case for Trace
Hugh O’Keeffe, Engineering Director, Ashling
Embedded debugging techniques have evolved from print to the more advanced techniques used today including run-control debug and real-time trace. This presentation will explain these two approaches and discuss the advantages of real-time trace and why it is suitable for validating and debugging complex systems including multicore architectures based on DesignWare ARC Processors. Specific use-cases will be presented showing how to use real-time trace to identify and solve common errors.
Embedded Vision Track
