Computer SolutionsOptimal Design, Reliable and Low Cost Embedded Solutions

Embedded systems are becoming advanced with increased complexity. Some of the common challenges faced by manufacturers and supplier are:

  • Achieving higher processing speed
  • Faster input and output data transfer
  • Low on-board memory
  • Increased development and testing cost
  • Harsh operating environment

LHP engineers, with more than decade’s experience, have mastered the skills in embedded systems, providing:

  • Optimized design, consuming less memory and faster execution rates
  • Modular approach for architecture design and development
  • Robust error handling and state-of-the-art testing methodology
  • Embedded hardware design with enclosures to operate effectively under harsh operating environments
  • Robust input and output and communication protocols

National Instruments Circuit Board

EMBEDDED SYSTEMS FOR AUTOMOTIVE

LHP Designed and developed a wheel chair accessible min-van ramp controller with the following features:

  • Designed for future expansion and advance features
  • Single firmware which works with three major OEMs
  • CAN Auto-detect feature and Common I/O Interface
  • Service tool interface for configurations and data analysis
  • Technology used Low level Embedded C, CAN, USB Communication and C# .NET WPF

MULTI-CORE SYSTEM DESIGN WITH AUTOSAR

Most of the automotive parts suppliers develop a new modular electronic controller that can accommodate one or more independent systems (Steering, ABS, Vehicle stability, etc.). The hardware modularity is implemented by one or two ECMs and replaceable IO modules. The challenge is to design and build software with the same modular architecture. LHP's expertise and proposed solution includes:

  • Utilizing AUTOSAR 4.x tools to build a modular software architecture, allowing executables to be easily replaced and relocated across 6 cores on 2 ECMs and supporting multiple hardware variants
  • Architectural design methodology that results in an optimal mapping of components and executables, bounded by asymmetric access to hardware resources, and the cost of inter-core and inter-ECU communications
  • Implement software redundancy so as to achieve fail safe and fail operational fault tolerance
  • Leverage LHP architecture and workflow experience to reduce R&D expenses and faster time to market

WINDOWS CE BASED EMBEDDED SYSTEM WITH GUI INTERFACE

LHP designed and implemented WINCE GUI applications to monitor CAN data on 3.2-inch LCD vehicle data monitoring device with following features:

  • GUI interface design for user to monitor CAN data and communicate with Engine Control Unit
  • Embedded report generation
  • Touch screen interface
