Enterprise integration technologies are a key contributor to improvingtime-to-market, cost, and design quality by a factor, which is the goal of theDARPA Rapid Prototyping of Application-Specific Signal Processors (RASSP)program [1]. The Lockheed Martin Advanced Technology Laboratories (ATL) RASSPteam developed a productivity improvement model, shown in Fig. 1, thatindicates the relative contributions of various RASSP technologies to theoverall improvement. Enterprise technologies address the entire 17% enterprisepartition, and more than half of the 30% reuse and model-year architecturepartition, thus accounting for at least 35% of the overall RASSP productivityimprovement.The ATL RASSP approach to implement enterprise systems is to extendcommercial technologies so the results are available to a broad base ofpotential users. Unlike current automation concepts which start atlater stages of the development cycle, the RASSP enterprise systemsupports the entire signal processor life cycle. Core concepts of theenterprise system include:Tools and tool frameworks integrated into an enterprise environmentProgram execution control through workflowsIntegrated data management functionsDesign reuseConcurrent engineering team supportIntegrated design engineering and manufacturing.The model-year architecture, which enables users to rapidly,efficiently upgrade systems with new technology, is supported in theenterprise system by a robust reuse management system. Manufacturinginterface and communication services elements of the enterprise systemprovide improved concurrent engineering support for distributedproduct teams. The enterprise system will be provided to commercial andaerospace users as products, including a reusable set of workflows forelectronics design, commercial tools supporting the enterprise systemenvironment, and utilities to enable users to customize the RASSPenterprise system for a particular organization or project.The enterprise system development cycle includesfour build cycles with increasing capabilities. The ATL team completed theBuild 2 implementation in May‘96. This implementation supports the processes associated with detailed hardware/software design, architecture design, and trade-off analyses. It is being used at Lockheed Martin and multiple government sites for benchmarking and evaluation. Results to date indicate 5:1 productivity improvements in the manufacturing interface, and 5–10% improvements in design engineering,which is growing with increasing level of utilization.
