The concept of network on chip (NoC) is a recent breakthrough in the system on chip (SoC) design area. A lot of work has been done to define efficient NoC architectures and implementations. In this paper, our goal is twofold. Firstly, we want to outline that the use of a NoC based shared-memory multiprocessor SoC challenges the application integrator(More)
Interconnect validation is an important early step toward global SoC (system-on-chip) validation. Fast performances evaluation and design space exploration for NoCs (networks-on-chip) are therefore becoming critical issues. A significant speed up of the global validation process for NoC-centric SoCs could be achieved by prototyping such systems on(More)
Heterogeneous MPSoC architectures can provide higher performance and flexibility with less power consumption and lower cost than homogeneous ones. However, as processor instruction sets of general heterogeneous MPSoCs are not identical, tasks migration between two heterogeneous processors is not possible. To enable this function, we propose to build one(More)
The computation and storage requirements for Deep Neural Networks (DNNs) are usually high. This issue limit their deployability on ubiquitous computing devices such as smart phones or wearables. In this paper, we propose ternary neural networks (TNNs) in order to make deep learning more resource-efficient. We train these TNNs using a teacher-student(More)
The Fsprit/OMI-COSY project defines transaction-levels to set-up the exchange of IP's in separating function from architecture and body-behavior from proprietary interfaces. These transaction-levels are supported by the “COSY COMMUNICATION IPs” that are presented in this paper. They implement onto Systems-On-Chip the extended Kahn Process(More)
For the design of classic computers the Parallel programming concept is used to abstract HW/SW interfaces during high level specification of application software. The software is then adapted to an existing multiprocessor platforms using a low level software layers that implement the programming model. Unlike classic computers, the design of heterogeneous(More)
This paper presents Disydent, a framework dedicated to system-on-a-chip (SoC) platform-based design for shared memory multiple instructions multiple data (MIMD) architectures. We define a platform-based design problem as a triplet (system, application, constraints) where the system is both an operating system (OS) and a hardware (HW) template that can be(More)
