摘要： The presently disclosed programmable fabric die includes a direct fabric die-to-fabric die interconnect interface column disposed in a sector of programmable logic fabric. Each row of the interconnect interface column includes at least one interconnect interface that is electrically coupled to a microbump. The microbump is configured to be electrically coupled to another microbump of another interconnect interface of another fabric die through an interposer. The fabric die may include multiple interconnect interface columns that each extend deep into the sector, enabling low latency connections between the fabric dies and reducing routing congestion. In some embodiments, the fabric die may include interconnect interfaces that are instead distributed throughout logic blocks of the sector.

摘要： In one embodiment, the present invention includes a system-on-a-chip (SoC) with first and second cores, interface logic coupled to the cores, chipset logic coupled to the interface logic, and a virtual firewall logic coupled between the chipset logic and the second core. The interface logic may include a firewall logic, a bus logic, and a test logic, and the chipset logic may include a memory controller to provide for communication with a memory coupled to the SoC. In some system implementations, both during test operations and functional operations, the second core can be disabled during normal operation to provide for a single core SoC, enabling greater flexibility of use of the SoC in many different implementations. Other embodiments are described and claimed.

摘要： Embodiments of the invention describe a host system capable of associating a PCIe device and another separate device to the same device identifier (e.g., device number). A cycle routing module or logic will identify an I/O transaction involving the device identifier, and route the transaction to one or both of the devices (or, in some instances, identify the I/O transaction as a configuration transaction, and simply update the cycle routing module/logic only). In one embodiment of the invention, a root port of the host system is configured to operate as the above described cycle router.Embodiments of the invention allow for devices to be “merged” into a single device for the host OS. For example, a peripheral devices coupled to the host system via a PCIe link may be “merged” with a peripheral devices coupled to the host system via another PCIe link or a SATA link.
摘要翻译：本发明的实施例描述了能够将PCIe设备和另一单独的设备关联到相同设备标识符（例如，设备号码）的主机系统。周期路由模块或逻辑将识别涉及设备标识符的I / O事务，并将事务路由到一个或两个设备（或者在某些情况下，将I / O事务标识为配置事务，并且简单地更新循环路由模块/逻辑）。在本发明的一个实施例中，主机系统的根端口被配置为作为上述循环路由器进行操作。本发明的实施例允许将设备合并到用于主机OS的单个设备中。例如，经由PCIe链路耦合到主机系统的外围设备可以与经由另一PCIe链路或SATA链路耦合到主机系统的外围设备合并。

摘要： Embodiments of techniques and systems for protected access to virtual memory are described. In embodiments, a protected memory management architecture (“PMMA”) may be configured to control accesses to protected physical memory. The PMMA may provide a protected virtual memory window for dynamic allocation of protected memory regions. During forward translation of virtual memory addresses, the PMMA may check a region ID of a process before allowing access. During reverse translation of a physical memory address, the PMMA may prevent accesses to protected physical memory addresses. The PMMA may also dynamically allocate physical memory to protected memory regions in virtual memory and may authenticate the physical memory as available before allocation. Other embodiments may be described and claimed.
摘要翻译：描述了用于保护访问虚拟存储器的技术和系统的实施例。在实施例中，受保护的存储器管理架构（“PMMA”）可以被配置为控制对被保护的物理存储器的访问。 PMMA可以为受保护的存储器区域的动态分配提供受保护的虚拟存储器窗口。在虚拟存储器地址的正向转换期间，PMMA可以在允许访问之前检查进程的区域ID。在物理存储器地址的反向转换期间，PMMA可以阻止对保护的物理存储器地址的访问。 PMMA还可以动态地将物理内存分配给虚拟存储器中的受保护的存储器区域，并且可以在分配之前认证可用的物理存储器。可以描述和要求保护其他实施例。

摘要： Embodiments of a memory scoreboard are presented herein. The memory scoreboard tracks memory requests for each rank and bank of memory being addressed. When there are no pending requests, the scoreboard provides an indication to an idle timer that begins a count down to close a current page of the memory. The idle timer can be configured dynamically to close memory pages and to address dynamically-changing code streams by tracking previous decisions made on page closes.
摘要翻译：记忆记分板的实施例在本文中给出。记忆记分板跟踪正在寻址的每个等级和存储体的存储器请求。当没有未决请求时，记分板向空闲计时器提供指示，该空闲计时器开始向下计数以关闭存储器的当前页面。可以动态配置空闲计时器以关闭内存页面，并通过跟踪页面关闭时做出的以前决定来解决动态变化的代码流。
