Title: Tactical Systems Common Operating Environment (TS-COE)


1
Tactical Systems Common Operating Environment
(TS-COE)
  • Team A1
  • Williamson, MacFarlane, Crabtree

2
Problem
  • Re-implementing Common Functions on multiple
    Projects with no requirements changes
  • Application Code locked to O/S and Hardware
  • Difficult to test Software reliably before Target
    Hardware is ready

3
Requirements/Assumptions
  • Maximum Use of COTS Processors and Operating
    Systems
  • Handle High Bandwidth Sensors and DSP
  • Application Domain
  • Static Threads
  • Static Scheduling
  • Simulation before Hardware

4
TS-COE
  • Tactical Systems Common Operating Environment
    (TS-COE)
  • Language, O/S Independent
  • Product and a Design Methodology
  • Simple to Implement
  • Improves Embedded, Real-Time Software
    Productivity and Reliability

Endpoints(implemented one or more per thread)
Sending thread(s)
Receiving thread (owns the pipe/endpoint)
Thread pops one mailbox at a time out of endpoint
and processes it
Mail
Registered mail goes in here when sent by
sending thread(s) (FIFO)
9
Design Methodology
  • Decomposition into Tasks
  • Inter-task Communication
  • Sequence Diagrams
  • Task State Machine Design
  • State Charts
  • Coding to Thread Templates
  • Simulation
  • Universal Test Driver (UTD)

10
Application Interfaces(documented in sequence
diagrams)
threads

FmControl
Arm
Mailboxes (across VME and shared memory)

Other Approaches
  • RT-COE
  • DAPRA Project
  • Large Scale Computing
  • RT-CORBA
  • DII COE Recommended for weapons system domain
  • Client/Server Distributed Object
