    摘要: A software infrastructure for providing an open digital services marketplace including a naming manager that enables a requesting task to refer to a desired resource using a name which is local to the requesting task and a router that forwards the request to an appropriate handler for the desired resource and that enables at least one additional task to be invoked in response to the request. The infrastructure includes a permission manager that compares a set of access rights of the requesting task to the desired resource to a set of permissions associated with the desired resource such that the access rights are kept separately from the reference to the desired resource. The desired resource, the requesting task, the additional task, and a set of additional components used to handle the request are each modeled as a resource defined by a corresponding set of meta-data which includes a set of attributes and a reference to a grammar for interpreting the attributes.

    摘要: A software system that provides access control to resources and that disassociates access rights to resources from references to resources to prevent the formation of large and unwieldy access control lists and to enable advanced decentralized security controls. The software system includes a repository that holds a resource descriptor for each resource including lock/permission pairs. Access to particular resources or groups of resources is provided by providing users with the appropriate keys. The keys are themselves are resources with resource descriptors in the repository. Access rights for users may be revoked by deleting keys from the repository. The software system also provides visibility fields for compartmentalizing access to resources. In addition, the software system provides authorizers that maintain audit trails when critical resource such as keys are passed among users and that enable advanced security control when passing resources among users.

    摘要: A dual ported replicated data cache. The cache is configured for storing input data blocks. The cache includes an augmenter for producing an augmented data block with parity information from the input data block, a first memory array for storing the augmented data block, and a second memory array for storing the augmented data block.

    摘要: A system and method for identifying a TLB entry having a physical address that is within a specified range are disclosed. The method includes obtaining a tentative TLB entry from a page table entry and accessing a physical address associated with the tentative TLB entry. The method further includes comparing the physical address of the tentative TLB entry with a predetermined range of addresses. If the physical address is within the finite range of addresses, an exception is invoked. In response to the exception, the physical address and/or an attribute of the tentative TLB entry can be modified. The tentative TLB entry can then be stored in a TLB.

    摘要: A method for configuring a signal path within a digital integrated circuit. The method includes transmitting an output from a first logic module, receiving the output at a second logic module, and conveying the output from the first logic module to the second logic module by using a configurable signal path. The configurable signal path is variable by selectively including at least one latch.

    摘要: A processing bypass directory system and method are disclosed. In one embodiment, a bypass directory tracking process includes setting bits in a bypass directory when a corresponding architectural register is written. The bits are selectively cleared in the bypass directory each cycle. The configuration of the bits is utilized to determine which stage of a bypass path processing information is at.
