SpecC stands for “specification description language based on C”.

What is SpecC? Design Methodology –for capturing and exchanging specifications of embedded systems –for consistency and continuity from specification to implementation System-Level Description Language –no distinction between HW and SW –specs and components in one syntax functional specs, architectural specs, and implementation design under same syntax and semantics –based on ANSI-C executable specification from the start Design Methodology –for capturing and exchanging specifications of embedded systems –for consistency and continuity from specification to implementation System-Level Description Language –no distinction between HW and SW –specs and components in one syntax functional specs, architectural specs, and implementation design under same syntax and semantics –based on ANSI-C executable specification from the start

Methodology Benefits HW/SW Co-Design –Partitioning/Scheduling in the System Level –“Ready to Product” quality of output (HDL,C) –Easy Optimization of Product Cost/Performance Design Tool Interoperability –Easy to build total design solutions IP-Centric Design –IP reuse for every specification models –Easy to publish: IP-spec by SpecC –Easy to reuse: Interface synthesis Education of System Architects –Established Design Style –Know-how transfer enabled via Design Legacy HW/SW Co-Design –Partitioning/Scheduling in the System Level –“Ready to Product” quality of output (HDL,C) –Easy Optimization of Product Cost/Performance Design Tool Interoperability –Easy to build total design solutions IP-Centric Design –IP reuse for every specification models –Easy to publish: IP-spec by SpecC –Easy to reuse: Interface synthesis Education of System Architects –Established Design Style –Know-how transfer enabled via Design Legacy Rapid, Easy, and Smooth Exploration in the Design of Embedded Systems, Ubiquitous Computing

Purpose Standardize specification description language Establish interoperability among design tools Promote industry-academia-wide collaboration Establish design methodology/guidelines based on SpecC Easy tailoring of design solutions for each application segments. Aggregation and Reuse of design IPs Standardize specification description language Establish interoperability among design tools Promote industry-academia-wide collaboration Establish design methodology/guidelines based on SpecC Easy tailoring of design solutions for each application segments. Aggregation and Reuse of design IPs
