Operating System for Runtime Reconfigurable Multiprocessor Systems

A Runtime Environment for Reconfigurable Hardware Operating Systems

We present a runtime environment that partially reconfigures and executes hardware tasks on Xilinx Virtex. To that end, the FPGA’s reconfigurable surface is split into a varying number of variable-sized vertical task slots that can accommodate the hardware tasks. A bus-based communication infrastructure allows for task communication and I/O. We discuss the design of the runtime system and its p...

Efficient task scheduling for runtime reconfigurable systems

Recent research indicates the promising performance of employing reconfigurable systems to accelerate multimedia and communication applications. Nonetheless, they are yet to be widely adopted. One reason is the lack of efficient operating system support for these platforms. In this paper, we address the problem of runtime task scheduling as a main part of the operating systems. To do so, a new ...

Performance Issues for Multiprocessor Operating Systems

A Multiprocessor Operating System Simulator

This paper describes a multiprocessor operating system simulator that was developed by the authors in the Fall semester of 1987. The sinmlator was built in response to the need to provide students with an en_t in which to build and test operatLug system concepts as part of the coursework of a third-year undergraduate operating systems course. Written in C++ [I], the simn]ator uses the co-routin...
