Extending the idea of preemptive multitasking to DPRS (Dynamic Partial Reconfiguration Systems) has far-reaching implications as many mechanisms supporting the concept, such as context saving and restoring, have to be built practically from scratch. This paper addresses previously neglected issues, related to design of effective preemption mechanisms for Flip-Flop-based and RAM-based hardware tasks...
In this paper, we present a hardware sharing method for design space exploration of multiprocessor embedded systems. In our prior work, we had developed a system-level design tool which automatically synthesizes communications among the processes. In this work, we have extended our tool so that the tool can automatically synthesize communications which realize sharing of hardware among different processes...
Advances in microprocessor technology provide sophisticated automotive control systems, in both realtime systems and information control systems. However, this trend brought the electronic control unit (ECU) complexity and large-scale software. One important solution will be `Integration' on both software and hardware side. Center for Embedded Computing Systems, Nagoya University (NCES) has performed...
Multicore systems-on-chip have become popular in the design of embedded systems in order to simultaneously achieve high performance and low power consumption. On the software side, real-time operating systems are necessary in order to handle growing complexity of embedded software. This paper describes requirements, design principles and implementation techniques for real-time operating systems to...
Multiprocessor designs have become popular in embedded domains for achieving the power and performance requirements. In this paper, we present principles and techniques for design and implementation of RTOS for embedded multiprocessor systems. We also present a system-level design toolkit for rapid design and evaluation of embedded multiprocessor systems.
