Abstract
A qualified burst cache facilitates burst mode data transfer between a first clock domain and a second clock domain by simplifying cache control structures. A cache is marked as qualified when full or there is no more data to be written to the cache, allowing burst data to be transferred out of said cache. The invention has applications in network adapter cards for transferring data between a host system bus and a network where the bus and network operate at different speeds and are therefore part of different clock domains.
