摘要： Disclosed is a storage system. A network interface device (NIC) receives network storage commands from a host. The NIC may cache the data to/from the storage commands in a solid-state disk. The NIC may respond to future network storage command by supplying the data from the solid-state disk rather than initiating a network transaction.

摘要： Disclosed is a coherent storage system. A network interface device (NIC) receives network storage commands from a host. The NIC may cache the data to/from the storage commands in a solid-state disk. The NIC may respond to future network storage command by supplying the data from the solid-state disk rather than initiating a network transaction. Other NIC's on other hosts may also cache network storage data. These NICs may respond to transactions from the first NIC by supplying data, or changing the state of data in their caches.

摘要： Various embodiments of the present invention provide systems and methods for reducing memory usage across multiple virtual machines. For example, various embodiments of the present invention provide methods for reducing resource duplication across multiple virtual machines. Such methods include allocating a shared memory resource between a first virtual machine and a second virtual machine. A data set common to both the first virtual machine and the second virtual machine is identified. A first set of configuration information directing access to the data set by the first virtual machine to a first physical memory space is provided, and a second set of configuration information directing access to the data set by the second virtual machine to a second physical memory space is provided. The first physical memory space at least partially overlaps the second physical memory space.

摘要： A variable length instruction pipeline includes optional expansion stages that can be included in the variable length instruction pipeline to avoid pipeline stalls. The expansion stages are removed from the variable length instruction pipeline when not needed to reduce the length of the pipeline, which reduces latency and other problems associated with long pipelines. For example, in one embodiment of the present invention, a variable length instruction pipeline includes a first pipeline stage, a first expansion stage, and a second pipeline stage. The second pipeline stage is configured to selectively receive instructions from the first pipeline stage or the first expansion stage if the first expansion stage holds an instruction.

摘要： Various embodiments of the present invention provide systems and methods for using providing memory access across multiple virtual machines. For example, various embodiments of the present invention provide methods for configuring a shared main memory region. The methods include providing a memory appliance that includes a randomly accessible bank of memory and a memory controller that is operable to maintain information in relation to a first virtual machine and a second virtual machine. The methods further include receiving a request to allocate a first portion of the bank of memory to the first virtual machine, and receiving a request to allocate a second portion of the bank of memory to the second virtual machine. The first portion of the bank of memory is identified as accessible to the first virtual machine, and the second portion of the bank of memory is identified as accessible to the second virtual machine.

摘要： A real-time, multi-threaded embedded system includes rules for handling traps and interrupts to avoid problems such as priority inversion and re-entrancy. By defining a global interrupt priority value for all active threads and only accepting interrupts having a priority higher than the interrupt priority value, priority inversion can be avoided. Switching to the same thread before any interrupt servicing, and disabling interrupts and thread switching during interrupt servicing can simplify the interrupt handling logic. By storing trap background data for traps and servicing traps only in their originating threads, trap traceability can be preserved. By disabling interrupts and thread switching during trap servicing, unintended trap re-entrancy and servicing disruption can be prevented.
摘要翻译：一个实时的多线程嵌入式系统包括处理陷阱和中断的规则，以避免诸如优先级倒置和重入的问题。通过为所有活动线程定义全局中断优先级值，并且仅接受优先级高于中断优先级值的中断，可以避免优先级反转。在任何中断服务之前切换到同一个线程，并且在中断服务期间禁用中断和线程切换可以简化中断处理逻辑。通过仅在其始发线程中存储陷阱和维护陷阱的陷阱后台数据，可以保留陷阱跟踪性。通过在陷阱维护期间禁用中断和线程切换，可以防止意外的陷阱重入和服务中断。
