Detailed Description

Design space database manager.

Design space database stores information about explored machine configurations for test applications.

The following information can be stored:

Machine architectures.
Implementations for architectures which define a working machine configuration.
Longest path delay estimates for implementations.
Area estimates for implementations.
Test applications for exploration.
Runtimes as clock cycle counts for application-architecture pairs.
Energy estimates for application-implementation pairs.
