  Allocation of software components on a heterogeneous computing platform
involves hard decisions; handling different types of computing units with
specific processing paradigms and a number of software components which require
specific resources. An allocation method which explores the design space to
provide a system architect with deployment alternatives in an early design
phase can have a significant impact on the utilization of underlying platform.
In this paper we present SCALL, an early prototype tool which uses heuristics
and AHP for weighted multi-objective design space exploration to support
systems architects in complex allocation decisions in early design phases.
