The increasing amount of computation in heterogeneous architectures (including CPU and GPU cores) puts a big burden on memory subsystem. With the gap between compute units and the memory performance getting wider, designing a platform with a responsive memory system becomes more challenging. This issue is exacerbated when memory systems have to satisfy a high volume of traffic generated from he...

Architectural decisions in embedded systems design are often based on assumptions about properties of the communication channels. For validating them rapid prototyping combined with run-time monitoring plays a major role. In this paper we present HarMonIC 1 – a reconfigurable hardware monitoring system for the run-time observation of communication channels. We will show how HarMonIC can be used...

Timing simulation is a key element in multicore systems design. It enables a fast and cost effective design space exploration, allowing to simulate new architectural improvements without requiring RTL abstraction levels. Timing simulation also allows software developers to perform early testing of the timing behavior of their software without the need of buying the actual physical board, which ...

In this paper, we propose a simultaneous meta-modeling protocol for both input and output spaces. We perform a reparametrization of the input space using constrained shape interpolation by introducing the concept of an α-manifold of admissible meshed shapes. The output space is reduced using constrained Proper Orthogonal Decomposition. By simultaneously using meta-modeling for both spaces, we f...

Metamodels and generators are typically applied to define development environments that produce code and other software related artifacts. Based on our experience they can also be used to produce other nonsoftware related artifacts, enable software and hardware co-design, support early level design space exploration, and automate testing activities. In this paper we describe – based on implemen...

In this paper, we introduce a compositive model of fabrication cost, network throughput and power consumption, to explore different 3D design options of 3D NoCs. The model allows partition of IPs across different dies in 3D stack. Based on the model an estimation tool, 3D-Partition, is created and validated by comparing its results with those obtained from NIRGAM. Effects of various 3D NoC arch...

Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (...
