SYSGO and STMicroelectronics demonstrate secure telematics

Thu, Dec 19, 2019

Real-time operating system (RTOS) for certifiable embedded systems company, SYSGO has jointly developed the Automotive Secure Gateway, based on STMicroelectronics’ Telemaco3P SoC.

The Telemaco3P SoC is an automotive processor for secure telematics and connectivity, which is combined with SYSGO`s PikeOS hypervisor-based RTOS, which brings avionics-grade safety and security to the automotive market, says the company.

The Telemaco3P platform ensures a secure connection between the vehicle and the cloud. Its asymmetric multi-core architecture is built upon powerful application processors as well as an independent controlled area network (CAN) control sub-system with optimised power management. Its ISO 26262 silicon design, embedded hardware security module and automotive-grade qualification up to +105 degrees C ambient temperature enable it to be used in a range of secure telematics applications supporting high-throughput wireless connectivity and over-the-air (OTA) firmware upgrades.

PikeOS extends the concept of secure telematics by encapsulating all communications channels and all applications in individual partitions, using a positive-security concept. This means that individual partitions cannot communicate with each other unless explicitly allowed and configured by the developer. The strict separation on the kernel level ensures that any malfunction or malicious attack will not impact the software running in partitions other than the one originally affected. PikeOS is currently the only RTOS/hypervisor certified to Common Criteria (EAL 3+). It has been used in a range of critical safety and security applications in the avionics, railway, and automotive industries.

The Automotive Secure Gateway implements a comprehensive security concept including a virtualised firewall, an intrusion detection system (IDS), fast and secure boot capabilities and a secure OTA update process. It supports secure cloud communications via LTE, as well as secured Wi-Fi, Bluetooth, Ethernet and CAN connectivity within the car.

At CES 2020, ST and SYSGO will demonstrate how the Automotive Secure Gateway can detect and effectively mitigate OTA attacks. Demos will take place at CES 2020 in Las Vegas, Nevada, USA, in the Automotive Grade Linux showcase in the Smart City exhibition (Westgate Booth 1815) and in SYSGO’s hospitality suite in the Westgate Hotel (floor 18, suite 1830).

Microchip delivers early access for RISC-V enables PolarFire SoC FPGAs

Wed, Dec 11, 2019

At this week’s RISC-V Summit in San Jose, California, USA, Microchip has announced an early access program for its PolarFire SoC.

Explaining the reason behind the programme, Microchip cited the trend towards compute-intensive gateways and edge devices which is driving the integration of traditional deterministic control applications with the additional embedded processing capabilities needed for smart and secure connected systems. The early access programme for the PolarFire SoC FPGA offers what is claimed to be the world’s first hardened real-time, Linux-capable, RISC-V-based microprocessor sub-system on the mid-range PolarFire FPGA family. According to Microchip, this brings low power consumption, thermal efficiency and defence-grade security to embedded systems.

Qualified customers can start designing now with Microchip’s Libero SoC 12.3 FPGA design suite and SoftConsole 6.2 integrated development environment (IDE) for the embedded developer. Customers can also debug embedded applications using Renode, a virtual model of the microprocessor sub-system.

The company believes that, in addition to driving innovation in the embedded space, as designers develop a new class of power-efficient applications, there will also be the opportunities to add “unprecedented capabilities” at the edge of the network for communications, defence, medical and industrial automation.

PolarFire SoC delivers power efficiency that is up to 50 per cent lower power than competitive devices in the industry, said Microchip. This reduces the bill of materials by eliminating the need for fans and heat sinks. It is believed to be the first SoC FPGA with a deterministic, coherent RISC-V CPU cluster and a deterministic L2 memory subsystem enabling Linux plus real-time applications.

The support of real-time and rich operating systems such as Linux is part of Microchip’s growing Mi-V RISC-V ecosystem, a comprehensive suite of tools and design resources developed by Microchip and third parties to support RISC-V designs. Ecosystem partners ready to support PolarFire SoC include WindRiver, Mentor Graphics, WolfSSL, ExpressLogic, Veridify, Hex-Five, and FreeRTOS as well as development tools from IAR systems and AdaCore.

EERAM retains data despite a power loss

Tue, Dec 03, 2019

Microchip has introduced a family of serial peripheral interface (SPI) EERAM devices that it says offers system designers up to 25 per cent cost savings over the current serial non-volatile RAM (NVRAM) alternatives.

Serial EERAM is a standalone serial SRAM that includes shadow non-volatile back-up. The SPI EERAM family introduces four SPI densities to Microchip’s EERAM portfolio, ranging from 64kbit up to 1Mbit.

They can be used for applications that require repetitive task data-logging and which must be able to automatically restore content if power is disrupted during processing. Target applications range from smart meters to manufacturing lines.

Current low-density (64kbit to 1Mbit) NVRAMs used for these data logs are typically the highest price-per-bit memory in the resulting end products, notes Microchip.

The EERAM standalone non-volatile RAM uses the same SPI and I2C protocols as serial SRAM, enabling devices to retain SRAM content during power loss without using an external battery. All non-volatile parts are invisible to the user. When the device detects power going away, it automatically transfers the SRAM data to non-volatile storage, moving it back to the SRAM once power returns.

In manufacturing lines, for example, stations handle up to millions of tasks over their lifetimes and lost data during a task can require overhauling or discarding items. EERAMs automatically store SRAM content in these settings, allowing the manufacturing line to resume where the task was disrupted.

The primary reason EERAM is available at a lower price point is the use of standard CMOS and flash processes. As the highest volume and most widely used processes and can offer the best reliability and lowest cost in the industry, explains Microchip.

Alternatives such as ferroelectric RAM (FRAM) use a specialty process, which results in higher costs and unstable long-term supply, argues Microchip.

This EERAM family comes with Microchip’s customer-driven obsolescence practice, which helps ensure availability to customers for as long as needed.

The 48L640 (64kbit SPI), 48L256 (256kbit SPI), 48L512 (512kbit SPI) and 48LM01 (1Mbit SPI) devices are available in eight-pin SOIC, SOIJ and DFN packages in volume production.
