Freescale Semiconductor introduced the MAC57D5xx, a new family of ARM® Cortex®-based single-chip, triple-core microcontrollers (MCUs) designed for automotive instrument clusters.

With more than 1.7x higher performance than any currently available automotive instrument cluster MCU, the new devices support complex graphics, including heads-up displays that previously required multiple components.

High-end automotive instrument clusters typically incorporate multiple external components, including a main processor, graphics unit, external SRAM, and dedicated circuitry to manage heads-up display warping and other sophisticated functionality. The cost and complexity of integrating these multiple parts previously restricted this functionality to the premium car segment.

Freescale and Broadcom Shrink their Ethernet MCU

Freescale Semiconductor and Broadcom Corporation together launched the Freescale Qorivva MPC5606E, a single-chip microcontroller (MCU) that integrates the Broadcom BroadR-Reach PHY. Its predecessor, the dual-chip MPC5604E, is currently in production. Freescale is sampling the new device now and expects that will be available in production quantities by the end of 2014.

Among other applications the device targets 360-degree “surround view” camera systems, which are used in applications such as park assist and blind spot detection. Automotive OEMS prefer peripheral cameras to be miniaturized and unobtrusive to maintain vehicle aesthetics. Smaller cameras can be more easily hidden within design features of the car, such as a front grill, bumper or wing mirror.

AUTOSAR is a partnership between automotive manufacturers and their suppliers as well as tool and semiconductor vendors.

The AUTOSAR Development Partnership, celebrating its 10th anniversary in 2013, has been developing an open, standardized software architecture for automotive electronic control units (ECUs) and an accompanying Methodology defining common exchange formats and description templates to enable a seamless configuration process.

Virtual Hardware In the Loop (vHIL): Earlier and Better Testing for Automotive Applications

By Victor Reyes, Technical Marketing Manager, Synopsys

Abstract

This article describes the concept of virtual hardware “in-the-loop” (vHIL). The goal of vHIL is to frontload the testing process by enabling software teams to create and run their software tests before the actual ECU hardware is available. Higher quality tests, higher quality software and a more streamlined “in-the-loop” flow is the intended outcome of this solution.

Besides describing how vHIL fits in the general Model-In-the-Loop (MIL) – Software-In-the-Loop (SIL) – Hardware-In-the-Loop (HIL) process, this article describes in some detail how a virtual prototype model created with Synopsys Virtualizer can be integrated with a MathWorks Simulink plant model. This integration is fundamental for enabling a vHIL solution.

Mentor Graphics Corporation has purchased AUTOSAR assets from Mecel AB, including the Mecel Picea AUTOSAR Development Suite. The acquired assets complement the existing automotive software solution from Mentor including the Volcano™ AUTOSAR products,   Mentor® Embedded Hypervisor, and Mentor Automotive Technology Platform (ATP), which enables Linux®-based automotive solutions, including GENIVI-compliant infotainment (IVI) solutions.  Terms of the acquisition were not disclosed.

Mentor Graphics partnered with Mecel to develop one of the industry’s first complete AUTOSAR 4.x solutions.

Mentor said its automotive software solutions enable a wide range of subsystems, including secure, homogenous and heterogeneous multicore and single-core ECUs.

dSPACE Offers New TargetLink Production Code Generator

dSPACE has released Version 3.5 of TargetLink, dSPACE’s production code generator. The new version includes support for Simulink® enum data types, which allow software developers to use descriptive names for parameters, thus improving model readability and maintainability.

For AUTOSAR-compliant development, the new release supports AUTOSAR Version 4.1.1. ECU resources and test efforts can be saved by generating multi-instantiable software components.

TargetLink 3.5 keeps installation files and project-specific extensions clearly separated. This provides increased process safety and transparency and also facilitates work in large, distributed groups.

ISO 26262 is a functional safety standard that replaces the older and more generic IEC 61508 standard for passenger vehicles.  ISO 26262 addresses hazards caused by malfunctioning behavior of electric and electronic safety related systems. 

The standard provides a well-defined, automotive-specific safety life cycle.  It also provides an automotive-specific, risk-based approach focused on automotive safety integrity levels, ASIL.  Finally, ISO 26262 provides requirements and recommended methods for validation of the safety levels. 

ISO 26262 defines a safety life cycle composed of three phases: the concept phase, development phase, and an “after the start of production” phase.

EEMBC and Volkswagen developing automotive benchmark standards for MCU energy efficiency

A prototype of EEMBC's automotive microcontroller efficiency benchmark includes test equipment from National Instruments connected to Renesas' V850E2/Fx4-L microcontroller.

The Embedded Microprocessor Benchmark Consortium (EEMBC) announced an expanded working group project with the Volkswagen Group to establish a microcontroller (MCU) energy-efficiency benchmark aimed at making automotive end products more energy aware and more robust.

“Volkswagen is continuing to chair the EEMBC Automotive working group and lend its expertise to ensure that the new benchmark reflects real-world system-design conditions and leads to improved efficiency,” said Dr. Volkmar Tanneberger, Volkswagen’s head of electric and electronic development.

Green Hills adds AUTOSAR support to INTEGRITY RTOS

Filed under News, Product News

 

Green Hills Software announced the availability of a compatible AUTOSAR (AUTomotive Open System ARchitecture) Application Programming Interface (API) for its safety- and security-certified INTEGRITY® real-time operating system (RTOS).

The availability of the AUTOSAR API for INTEGRITY—combined with APIs for OSEK and POSIX—provides automobile manufacturers a path to address the growing dilemma of ECU (Electronic Control Unit) complexity facing vehicles today.

80-plus ECUs

The modern automobile has upwards of 80 microprocessor-based ECUs and the number continues to grow due to legacy design practices. This growth is negatively impacting vehicle cost, complexity, quality and time-to-market.
