This article proposes a modification of the standard Linux scheduler for a support of a reconfigurable heterogeneous multiprocessor system. The standard Linux scheduler is limited to a homogeneous multiprocessor system only. The addition of the processing core with a different feature requires modification of a decision algorithm of the scheduler as a heterogeneous task cannot be executed on any processing...
Two new multiprocessor architectures to accelerate the simulation of multi-agent worlds based on the massively parallel GCA (Global Cellular Automata) model are presented. The GCA model is suited to describe and simulate different multi-agent worlds. The designed and implemented architectures mainly consist of a set of processors (NIOS II) and a network. The multiprocessor systems allow the implementation...
Computer architectures are increasingly turning to parallelism and heterogeneity as solutions for boosting performance in the face of power constraints. As this trend continues, the challenges of simulating and evaluating these architectures have grown. Hardware prototypes provide deeper insight into these systems when compared to simulators, but are traditionally more difficult and costly to build...
This paper presents a multiprocessor system on FPGA that adopts Direct Memory Access (DMA) mechanisms to move data between the external memory and the local memory of each processor. The system integrates all standard DMA primitives via a fast Application Programming Interface (API) and relies on interrupts having also the possibility to manage a command list. This interface allows to program the...
