Core Technology
Architecture Neutral Distribution Format
4
What is ANDF
Architecture Neutral Distribution Format

• A low-level abstraction of high-level languages
• Rich enough to model all language constructs
• Completely independent of target architecture
• Developed by UK MoD Defense Research Agency as an
  enabling technology for developing portable
  software in C
• Enriched by DDC-I for Ada and C (ANDF 4.0)
• ANDF 4.0 is an X/OPEN standard

5
Open Standards

• Ada
• C
• ELF
• DWARF
• ANDF
• OMI Host/Target Protocol

6
Key Features

• Multi language, Multi Host, Multi target
• Eclipse Ready
• Ada 95 certified (validated) to ACATS 2.2
• Ada 95 annexes A through D, and H
• A Predefined Language Environment
• B Interface to Other Languages
• C Systems Programming
• D Real-Time Systems
• H Safety and Security

7
Key Features contd

• C Compiler ISO-9899 Compliant with Additional
  Lint-like Checks
• Embedded Subset of ISO C Standard
• Excludes Multiple Inheritance, Run-time Type
  Identification

Multi-Language Debugger
Key Features

• Advanced GUI and sequential debugger
• Full support for Ada and C symbolic debugging
• Full support for machine level debugging
• Designed for true real-time debugging
• Extensive task debugging facilities
• Powerful command language
• Configurable to your hardware
• Supports debugging of optimized programs

12
Benefits
Application Developers

• Software component reuse
• Across programming languages
• Target processor upgrade
• Same compilers - no major rewrite of application
• Change host development platform
• Whenever cost-efficient seen in isolation
• All of the above leads to
• Shorter time-to-market for new applications
• Extended life, applications will not become
  obsolete with the hardware
• Risk reduction through re-use and upgradeability
• Cost reduction

13
Benefits
Microprocessor Manufacturers

• A new microprocessor just calls for ONE new
  installer
• All languages become available
• Applications easy to port Basically same
  compilers
• This leads to
• Risk reduction
• Lack of compilers previously was a show stopper
• Cost reduction
• Only one installer needs to be provided rather
  than several compilers

14
Benefits
Compiler and Tool Manufacturers

• A new programming language just calls for ONE
  producer
• All targets are covered
• New processors (host or target) call for ONE
  installer only
• All languages are covered
• Most compiler and tool components shared between
  languages
• This reuse leads to
• Shorter time-to-market
• Cost reduction
• Risk reduction

15
Third Party Integrations

• Wind River VxWorks RTOS
• Ardence RTX RTOS
• LynuxWorks LynxOS RTOS
• ARTiSAN UML Tools
• Vector Module Testing Tools
• Macraigor JTAG Probes
• Abatron JTAG Probes
