چکیده
In shared System-on-chip(SoC) bus systems, arbiters are mandatory to deal with bus contentions while providing a hard real-time guarantee. In this paper, we propose a shared bus arbitration algorithm, called adaptive dynamic and real-time guaranteed arbitration algorithm. It allows high bus utilization and proper bandwidth allocation while guaranteeing hard real-time requirements. Comparisons are made between the proposed arbitration scheme and Static Priority, RoundRobin arbitration and Lottery on Virtex5 from Xilinx. Experimental results show that the proposed arbitration algorithm outperforms several commonly-used algorithms.

متن کاملNew Trends and Developments in Automotive System
Performance of Multicore Shared bus Embedded Controller depends on how effectively the sharing resources can be utilized. Common bus in System on Chip is one of the sharing resources, shared by the multiple master cores and also acting as a channel between master core and slave core (peripherals) or Memories. Arbiter is an authority to use the shared resource (Shared bus) effectively, so perfor...

This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...
متن کاملApplying stochastic modeling to bus arbitration for systems-on-chip
In this article we implement a stochastic modeling technique for simulating the communication between processors and arbitration among buses for an embedded SoC. The stochastic models implemented with queues have been used to estimate, through simulation of different arbitration policies, the power consumption and delays, as well as estimate average or worst case scenarios that could occur with...
متن کاملEvaluation of Communication Latency Invmebus - Based Real - Time Control
Although the VMEbus has been widely used for real-time control systems , its real-time performance has not been evaluated thoroughly. This paper evaluates the latency of interprocessor communication in a VMEbus-based real-time control system. To minimize communication latency, mixed priority/round-robin (MPR) bus arbitration is proposed and its performance is evaluated along with standard PRI a...
