Current multiprocessor systems on chip (MPSoC) architectures integrate a massive number of IPs that need to exchange data in complex and diverse synchronization ways. The key challenge when designing MPSoC is that the communication architecture needs to be decided at the beginning of the design, before all the details about mapping the application on the architecture are known. These early decisions...
The high complexity of current multi-processor system on chip (MPSoC) impels the designers to model and simulate the system components and their interaction in the early design stages. High level modeling usually requires less modeling effort and executes faster. In this paper we propose high level communication models that allow early MPSoC design, performance estimation and evaluation of the application's...
Multimedia applications require heterogeneous multiprocessor architectures with specific I/O components in order to achieve computation and communication performances. The different processors run different software stacks, which are composed by the application s tasks and a hardware dependent software (HDS). The HDS contains an operating system, a specific communication library and a hardware abstraction...
Multimedia applications require heterogeneous multiprocessor architectures with specific I/O components in order to achieve computation and communication performances. The different processors run different software stacks made of the application code and the hardware dependent software layer. Developing this software usually makes use of a high level programming environment that does not handle specific...
In this paper, we introduce a mixed hardware -software architecture model to abstract hardware-software interfaces of multithreaded heterogeneous multiprocessor architecture with specific hardware I/O. We use Simulink environment as modeling language to capture this representation. We generate two intermediate simulation models called Virtual Architecture and Transaction Accurate to validate the software...
System-level design methodologies have been introduced as a solution to handle the design complexity of embedded multiprocessor SoC (MPSoC) systems. In this paper we describe a system-level design flow starting from Simulink specification, focusing on concurrent hardware and software design and verification at four different abstraction levels: Simulink Combined Algorithm and Architecture Model (CAAM),...
