    摘要： Embodiments of the invention make the issuance of trustworthy device claims available to client devices as a service, so that a client device to which device claims are issued may use the device claims in relation to an attempt to access a network application. The service may conduct an assessment of the device's characteristics and/or state, characterize the results of this assessment in device claims, and issue the device claims to the device. The service may be accessible to a client device from outside administrative boundaries of an entity that makes a network application accessible, and thus may be useful to entities making network applications accessible in business-to-consumer (B2C) and business-to-business (B2B) topologies, such as over the publicly accessible Internet.

    摘要： A distributed system in which time-dependent credentials are supplied by controllers that operate according to different local times. Errors that might arise from the controllers generating inconsistent credentials because of time skew are avoided by identifying credentials generated during transition intervals in which different ones of the controllers may generate different credentials at the same absolute time. During a transition interval, controllers and other devices may use credentials differentially based on the nature of the authentication function. Each controller may periodically renew its credentials based on self-scheduled renewals or based on requests from other devices, such that renewal times are offset by random delays to avoid excessive network traffic. Controllers may determine which credential is valid for any given time, based on a cryptographically secure key associated with that time and information identifying the entity that is associated with that credential.

    摘要： An interface connects data processing components and data memories that support data transfer at different data rates. The interface handles complex timing and asynchronous delays associated with these different rates of data transfer. The interface may be used to connect data processing components that operate at 133 MHz with DDR SDRAM devices that operate at 200 MHz to 266 MHz data rates.

    摘要： A video memory controller controls a DRAM (dynamic random access memory) used as a video memory and as a system memory. The video memory and the video memory controller are normally a part of a video system which includes a data processor, the video memory, the video memory controller, a CRT controller and a CRT display device. The video memory controller includes a row address latch for storing a row address from the data processor, a column address latch for storing a column address from the data processor, a refresh address register for storing a memory refresh address and a display update generator for sequentially generating the addresses necessary for update of the CRT display. A multiplexer couples the proper address to the video memory under control of a memory cycle generator which generates the timing of the memory refresh and display update. An arbiter device enables only one of the possible memory cycles at a time. The data processor has higher priority over memory refresh during an initial period of each horizontal line of the display, while the memory refresh has higher priority over the data processor during the final period of each horizontal line.
