摘要： A bridge circuit adapted to be associated with a PCI and a secondary bus circuits which bridge circuit includes circuitry for storing an indication that a particular PCI bus master has attempted an access of the secondary bus and has been forced to retry that access, circuitry for masking any retry until the bus is again available, and circuitry for providing an interval during which a retrying PCI bus master is guaranteed access to the secondary bus in favor of a bus master on the secondary bus after the bus is relinquished so that a sequence of retry operations causing a loss of bandwidth on the PCI bus is not generated.

摘要： A bridge circuit providing for efficient data transfer between a first bus and a second bus in a computer system. The bridge circuit receives an address indicating a memory location storing a data segment requested to be transferred from the first bus to the second bus. Fetch circuitry fetches the requested data from the first bus and prefetches one or more additional data segments stored in memory locations sequentially following the memory location storing the requested data. The prefetched data segments are stored in a buffer for immediate access by subsequent data transfer requests. Supply circuitry transfers each data segment from the buffer to the second bus in response to receiving an address corresponding to the particular data segment on the address input circuitry.

摘要： A synchronizing circuit translates signals in a slow clock domain into a fast clock domain. The frequency of the slow clock is a submultiple of the fast clock frequency. A synchronizing pulse signal is developed at the frequency of the slow clock, but is phase synchronized to the fast clock. The synchronizing pulse signal is employed to gate the signal in the slow clock domain so that it is synchronized in the fast clock domain. In a system where the ratio between the fast clock frequency and slow clock frequency is determined by a frequency divisor signal, a snooping circuit is employed to capture the frequency divisor signal to achieve rapid synchronization between the clock domains.

摘要： A latching mechanism captures an address transmitted on a multiplexed address/data bus and preserves it for the full bus cycle. A transparent latch with a multiplexed feedback path allows the address to be quickly captured and decoded. An additional multiplexer and latch cooperate with the first mentioned latch to keep the address stable for a sufficient time to allow latching by slower memory elements. Additional elements are provided to automatically increment the address for multiple data burst operation.

摘要： Systems and methods for long-term non-volatile non-rotating optical storage of digital information rely on storage elements that include optical storage media, an access subsystem configured to access bits of information from one of the storage elements, and a support structure configured to support multiple storage elements. A laser used to retrieve and/or record bits of digital information may be moved along two orthogonal dimensions while the storage element is non-rotating.
