GENESYS – GENeric Embedded SYStems(Instruction how to build your embedded systems architecture)GENESYS:

is a reference architecture template providing specifications and requirements to design a cross domain embedded systems architecture for your application.architecture style supports a composable, robust and comprehensible, component based framework with strict separation of computation from message based communicationdistinguishes between 3 integration levels:

• Chip Level (IP cores communicate via a deterministic Network-on-a-Chip)• Device Level (Chips communicate within a device)• System Level (Devices communicate in an open or closed environment)

GENESYS Reference Architecture Solves 3 Challenges:Complexity Management

Management of ever increa-sing cognitive complexity of embedded systems is a major concern of all applica-tion domains

Lift the design process to a higher level of abstraction.

Self-contained HW/SW components, exclusively communicating by exchange of messages

Reuse of components based on their interface specification

Establish a framework of:• Fault containment • Error containment • Selective re-start of

components failed (transient faults)

Replication of components

Security addressed at all levels of architecture

Energy efficiency provided:•Technology agnostic, model-driven design style supporting migration of stable component from SW on a CPU to ASIC

•Reduce of power require-ments of components

•Turn-off of un-needed com-ponents

Robustness

Deliver an acceptable levelof service also in case offaults and operator mistakes

Energy Efficiency

Energy efficiency is of utmostconcern in mass market of mobile devices
