Virtual Hardware for Operating Systems
Developing an operating system on bare hardware is diicult due to an inhospitable development environment, long edit-compile-run-debug times, and the need for extra target hardware. This paper contributes general techniques for creating virtual hardware for operating systems development. The virtual machine is realized on top of UNIX and is a close approximation of real hardware, including inte...
متن کاملA hardware supported operating system kernel for embedded hard real-time applications
In this paper a concept of the kernel, i.e., the time critical part of a real time operating system and its dedicated co-processor, especially tailored for embedded applications, are presented. The co-processor acts as a system controller and operates in conjunction with one or more conventional processors in hard real time environments. It is composed of three physically and clearly separated ...
متن کاملPerformance and the Single/multi{processor Operating System Process Subsystem
Operating systems depend on process subsystem performance, which we analyze in Choices. We use compile time specialization to optimize both single and multiprocessor performance within a single design. We partition critical sections into two types, and compose independent control mechanisms to produce high performance, specialized locks. We select heavily used process operations and justify new...
متن کاملBeyond Processor-centric Operating Systems
By the end of the decade, computing designs will shift from a processor-centric architecture to a memorycentric architecture. At rack scale, we can expect a large pool of non-volatile memory (NVM) that will be accessed by heterogeneous and decentralized compute resources [3, 17]. Such memory-centric architectures will present challenges that today’s processor-centric OSes may not be able to add...
متن کاملDesign a Hardware Mechanism to Utilize Multiprocessors on a Uni-processor Operating System
The multiprocessor architecture for multimedia embedded systems becomes more popular, because of processor design and fabrication evolution. However the interprocessor communication is still an important problem in multiprocessor environments. In this paper, we propose a hardware interprocessor communication mechanism for a multi-core FPGA chip. Although the hardware/software develop tools do n...
