ISO 26262 & Automotive Electronics Development

Compliance standards, especially those that involve relatively new functional safety elements, will likely add additional requirements to the development process. But ISO 26262, in particular, will add more than new requirements to the product life cycle for automotive hardware-software systems. This Functional Safety standard will act as a framework impacting integrated requirements traceability, risk management, validation, verification, documentation and collaboration throughout the systems engineering “V” model life cycle process (see Figure). ISO 26262 will also require the qualification of tools used to create automotive systems. This paper examines the impact of the standard on the development process and support tool chains for automotive electronics.

Eliminating Blind Spots in Commercial Trucking with IoT

Technology is becoming a critical business tool for truck manufacturers, fleet operators, and service centers. On-board diagnostics and telematic systems are a first step, but only provide a singular view and limited scalability. A more comprehensive view of truck health delivers reliability, improved uptime, and faster repairs; but this requires examining a larger and richer set of engine data together with external sources.

The Reality of Application Security: Scare Tactics or Genuine Threat?

Guardians of application security have perhaps become slightly immune to the fearful messages of cybersecurity vendors. The combination of ‘Big Data’ with an exponentially growing Internet of Things (IoT) would seem to provide the perfect storm conditions for the exploitation of vulnerable code streams. Read this whitepaper about the reality of AppSec to discover what are the real risks and how to mitigate them.

Generalized Query Tool for Accessing the Database of the Mars Relay Operations Service (MaROS)

The Generalized Query Tool for accessing the database of MaROS can be utilized in three modes: (1) batch mode where a user's authentication data is inserted directly along with a desired query to the database, (2) interactive mode where a desired query is known and can be entered directly, and (3) interactive mode with a query “wizard” that walks a user through the steps needed to construct a valid query to the database. In all three cases, the successful execution of the script results in data from the MaROS database being made available to the user in a comma-separated output file. For new users, it is recommended to use the third mode to build a sample query and then tailor that as desired for use with the first or second modes.

High-Performance Fault-Tolerant xEmbedded Computing (HPFEC) Benchmark Suite

This work arises out of the Next Generation Space Processor (NGSP) project, a collaborative effort among several NASA centers and the Air Force Research Laboratory. The goal of NGSP is to develop the next generation of radiation-hardened, fault-tolerant, space-worthy computing systems consisting of hardware and system software. To drive and evaluate the design, each of the NGSP collaborators contributed benchmarks. This article describes the benchmarks developed at the Jet Propulsion Laboratory (JPL). Collectively, these benchmarks are called the HighPerformance Fault-Tolerant Embedded Computing (HPFEC) benchmark suite.

JPF-NAS Extension of Java Pathfinder

Java PathFinder (JPF) version 7 provides basic support for verifying the distributed Java applications. It can receive a distributed Java application as input that is perceived as multiple Java processes. However, JPF does account for communication between processes of the distributed application, and it thus cannot be used to verify any realistic distributed Java application. Applying JPF on distributed applications requires a model of inter-process communication (IPC) and process aware scheduling.

Institutional Budgeting Tool (IBT)

The Jet Propulsion Laboratory's Institutional Budgeting Tool (IBT) was designed and developed to meet the needs of JPL's budget planners, numbering 1,600, who required a robust and state-of-the-art budgeting application. JPL's budgeting process had been constrained by legacy tools that presented usability and performance issues and lacked critical innovative budgeting features. IBT delivered superior user experience, system performance, and modern features necessary for essential laboratory budgeting.
