QR0001 QuickRing Data Stream Controller

PRELIMINARY

Data Stream Controller

General Description

QuickRing is a point-to-point data transfer architecture de-

signed to facilitate high speed data streams The QuickRing

architecture can be applied both inside the chassis as well

as outside the chassis environments to increase data

throughput Each QR0001 QuickRing Controller node in the

ring is capable of streaming up to 231 MSamples s per sig-

nal line simultaneously including protocol overhead This

device is intended for use in applications that handle high-

bandwidth data streams associated with graphics uncom-

pressed video disk arrays high-speed local area networks

multiprocessor systems and to interconnect peripherals

over a few meters of cable The QR0001 QuickRing Con-

troller can be used to augment the performance of tradition-

al backplane buses in personal computers workstations

and high-end systems The QR0001 is useful for routing

high-bandwidth streams in systems that are larger or topo-

logically more complex than bus-based systems
