摘要： A method for look-ahead load pre-fetching that reduces the effects of instruction stalls caused by high latency instructions. Look-ahead load pre-fetching is accomplished by searching an instruction stream for load memory instructions while the instruction stream is stalled waiting for completion of a previous instruction in the instruction stream. A pre-fetch operation is issued for each load memory instruction found. The pre-fetch operations cause data for the corresponding load memory instructions to be copied to a cache, thereby avoiding long latencies in the subsequent execution of the load memory instructions.
摘要翻译：一种用于预先加载预取的方法，可减少由高延迟指令引起的指令停顿的影响。通过在指令流停止等待指令流中的先前指令的完成的情况下，通过搜索指令流来执行加载存储器指令来实现预先加载预取。为发现的每个加载存储器指令发出预取操作。预取操作导致相应的加载存储器指令的数据被复制到高速缓存，从而避免后续执行加载存储器指令的长时间延迟。

摘要： Computer apparatus includes an execution unit for executing a sequence of instructions which may include a speculative load instruction, a memory for storing data required by the instructions for execution, a low latency data cache for holding data accessed in the memory in response to the instructions, a low latency data buffer for holding speculative data accessed in the memory in response to the speculative load instruction, and a controller. The controller loads the speculative data from the memory into the data buffer in response to the speculative load instruction when the speculative data is not present in the data cache or the data buffer, and loads the speculative data from the data buffer into the execution unit. The speculative data may be loaded from the data buffer into the execution unit when the speculative load instruction is executed or when the speculative load instruction is committed. The speculative data is supplied to the execution unit with low latency and without contamination of the data cache.

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 communications protocol using group ordered message processing is disclosed. According to the protocol, a sending application groups messages together. The messages within the groups are then processed by a receiving application in the order received, but the groups themselves are processed in the order sent. More specifically, the invention pertains to a method for receiving messages at a processor node from another processor node via a plurality of communication paths. The method includes the steps of: receiving a message having a required number of messages value, comparing the required number of messages value with a number of processed messages, and determining whether the message is ready to be processed based on the result of the comparison. The invention can also be implemented as an apparatus. As an apparatus, the invention pertains to a processing node for a communication system which transmits messages between processing nodes interconnected by multiple communication paths. The invention has numerous applications, including transaction processing, parallel processors, distributed shared memory systems, asynchronous RPC mechanism, and bulk data transfer.

摘要： The op-code bandwidth limitation of computer systems is alleviated by providing one or more vector buffers. Data is transferred between memory and processor registers in a two part process using the vector buffers. In a first part, a vector request instruction initiates buffering of data by storing data in control registers identifying a set of data elements (a vector) in the memory. When the identifying information is loaded in the control registers, a vector prefetch controller transfers elements of the vector between the memory and a vector buffer. In a second part, vector element operation instructions transfer a next element of the vector between the vector buffer and a specified processor register for use in arithmetic or logic operations.

摘要： A software system with task-specific flexible bindings that enhance the ability to dynamically add and remove resources from availability to tasks and that eliminates the need for coordination of globally unique names. The software system includes a task-specific name space which corresponds to a task executing in the software system. The task-specific name space holds flexible bindings each of which associates a task-specific name used by the task to refer to a desired resource or a set of one or more resources of the computer system and to information that describes the desired resource. The software system includes a resource mediator that obtains a message from the task. The resource mediator keeps information for each resource that identifies a resource handler task for the desired resource by resolving the task-specific name using the flexible binding.

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.
