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

Methodology Benefits
Rapid, Easy, and Smooth Exploration in the Design
of Embedded Systems, Ubiquitous Computing

• 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

Purpose

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