Rapid Prototyping of Application Specific Signal Processors Program

摘要

This report discusses the results of the Texas Instruments (TI) Rapid Prototypingof Application Specific Signal Processors (RASSP) study efforts to identify a development process consistent with the RASSP program methodology. In this study, we defined the concept of a library based system design approach with in-cycle and out-of-cycleopment of library elements. This report discusses this approach and the issues associated with system, hardware, and software design tools, and manufacturing foundry interfaces required to support a library based system development approach. The library based development concept is defined and the modularity and partitioning of a domain specific architecture is discussed. A description of the library elements supporting a library based system design approach is provided. Requirements, issues, and approaches to signal processing system design analyses and tradeoffs, and system simulation and validation are discussed. Data base representation issues, frame-words, and interfaces required to provide a seamless RASSP development environment are identified. Reusable software and library element development issues are addressed. Hardware CAD issues associated with library element development, system analyses, simulation, and validation are discussed. Manufacturing foundry CAD, CIM, design tool interfaces, and test issues are also discussed. A summary of the effort and recommendations for implementation are also included.
