Pave Pillar architecture incorporates a Common Signal Processor CSP concept as a key building block of a USAF advanced avionics suite. This CSP concept embodies the use of standard internal interfaces, a family of modules, use of the programming language Ada to express application program for the data processors within CSP, and the use of a Graph Notation to represent signal processing functions for the signal processing components of CSP. The modularity permits upgrading any hardware or software component with minimal disruption to the rest of the design. CSP is an open architecture in that the interfaces and module specifications are non-proprietary and can be built by other vendors. The paper addresses the system concept, hardware architecture, and software philosophy comprising the CSP System. It describes in general terms how the CSP hardware works and its expandability. Existing modules are listed and potential future models identified. A brief description of the Graph Notation and its advantages is provided. The CSP local operating system capabilities and use are summarized. Application studies to determine the suitability of the CSP concept for different avionic applications such as radar, electronic warfare, communications, and electro-optical sensors are summarized. The role of MIL-STD-1750A processors in CSP and their limitations are touched on, and upgrades to 32-bit machines discussed.
