摘要： Systems, methodologies, media, and other embodiments associated with externally trapping transactions are described. One exemplary system embodiment includes an external virtualization logic configured to be operably connected to a processor that does not include internal virtualization support. The example system may include a data store for storing a trappable memory address and a transaction that causes the external virtualization logic to produce a trap.

摘要： Systems, methodologies, media, and other embodiments associated with a system configured with a trap mode register, multiple interrupt vector address registers, and multiple interrupt vector tables are described. One exemplary system embodiment includes a logic for initializing the trap mode register, for initializing interrupt vector address registers, and for initializing interrupt vector tables. When a trap occurs in a computer configured with the exemplary system, the trap mode register may select, based, for example, on the trap type or a trap data, an associated interrupt vector address register to provide an address of an interrupt vector table through which a trap handler can be invoked.

摘要： Techniques are provided for allocating a plurality of resources on a chip to a plurality of partitions in a partitionable computer system. In one embodiment, a resource allocated to a first partition generates a physical address in an address space allocated to the first partition. A partition identification value identifies the first partition. The first partition identification value is stored in the first physical address to produce a partition-identifying address, which may be transmitted to a system fabric. In another embodiment, a transaction is received which includes a source terminus identifier identifying a source device which transmitted the transaction. It is determined, based on the source terminus identifier, whether the source device is allocated to the same partition as any of the plurality of resources. If the source device is so allocated, the transaction is transmitted to a resource that is allocated to the same partition as the source device.

摘要： Systems, methodologies, media, and other embodiments associated with external virtualization are described. One exemplary system embodiment includes an emulation logic located external to an integrated circuit to which it may be operably connected. The example emulation logic may include a virtualization logic that is configured to virtualize a portion of a function performed by the integrated circuit. The portion may be identifiable by an address associated with the portion. The example emulation logic may also include a data store that is operably connected to the virtualization logic and that is configured to store a state data associated with virtualizing the portion of the function.

摘要： A system for implementing polygon edging of objects in a graphics display. In a first pass, the system renders the polygon fill with z-buffer comparison and replace enabled, however, for each pixel written to the display frame buffer and z-buffer, an edging plane bit for the pixel is set. A second pass renders the polygon edges with z-buffer comparison and z-buffer replace enabled and uses the edging plane bit as a virgin bit. A third pass re-renders the polygon fill, but only resets the edging plane bit for each pixel. The system may also use a virgin bit available in the z-buffer as the edging plane bit.

摘要： A computer system maintains a list of tags (called a Global Ownership Tag List (GOTL)) for all the cache lines in the system that are owned by a cache. The GOTL is used for cache coherence. There may be one central GOTL. Alternatively, the GOTL may be distributed, so that every device that can request a copy of memory data maintains a local copy of the GOTL. The GOTL can be limited to a relatively small size. For a limited size list, a tag may need to be evicted to make room for a new tag. A line associated with an evicted tag must be written back to memory.
