This work evaluates task allocation strategies based on bin-packing algorithms in the context of multiprocessor systems-on-chip (MPSoCs) with task migration capabilities, running soft real-time applications. The task migration model assumes that the whole code and data of the tasks are transferred from an origin node to the chosen destination node. We(More)
Regarding MPSoCs, dynamic task allocation and task migration are still open research areas and, for both of them, there is no clear memory organization winner. While bus-connected systems commonly use a shared memory paradigm, NoC-based ones easily allow the exploration of distributed memory alternatives. This paper proposes a hybrid memory organization for(More)
This chapter presents a study on the performance and energy consumption arising from distinct memory organizations in an NoC-based MPSoC environment. This evaluation considers three sets of experiments. The first one evaluates the performance and energy efficiency of four different memory organizations in a situation where a single application is executed.(More)
This paper presents a virtual platform for the development and test of application software, low-level software, and hardware components for an MPSoC (Multiprocessor System-on-Chip) platform, where components are interconnected by a network-on-chip (NoC). The environment is aimed at the development of multithread real-time embedded applications in Java(More)
ABSTRACT The paper presents a semi-passive UHF RFID tag chip developed to meet the restrictive requirements for Electronic Vehicle Identification application. The use of an external power supply allows the tag to achieve longer communication ranges even though additional features such as communication data encryption have been added. The system exploits(More)
