The document introduces Real-Time Software Components (RTSC), a C-based software component model for developing reusable real-time software for diverse embedded platforms without compromising performance. RTSC uses a dual-existence approach where component meta-code runs on rich client platforms and manages the lifecycle of component target-code, which runs on resource-limited hardware. This allows for design-time optimizations and tooling opportunities while standardizing optimizations for embedded targets. Texas Instruments is taking its XDCtools, which currently support thousands of customers, open source to further RTSC adoption.

RTSC Components
Key Characteristics
 dual-existence
• meta-code: runs on rich client platforms
• target-code: runs on resource limited HW
 meta-code manages component lifecycle
• build of component (including target-side)
• integration during application assembly
• monitoring during test and after deployment
Benefits
 standardizes design-time optimizations
• transparently binds alternate implementation
• objects can be created at design-time
• no embedded runtime requirements
 enables unlimited tooling opportunities
• meta-code can proxy for target-code
• components differentiate in meta-domain
