    摘要： A method and apparatus tracks packets and reliably transmits data over a computer transmission system with a reduced amount of memory needed in the transmission interface. The invention eliminates the need to keep all the packets of data queued until the acknowledge message for that data has arrived. Instead, it keeps track of how many packets have been sent and which packets correspond to the end of a message, marking them off when acknowledge messages are received. If packets are lost, the invention determines which packet were lost, backs up to the lost packet, re-fetches the data and resends it. Embodiments of the present invention eliminate the need to queue packets, reducing silicon size and allowing the available bandwidth of the output bus to be more fully utilized.

    摘要： Concurrent read access and exclusive write access are provided in a shared memory architecture to permit one or more devices in the shared memory architecture to maintain read access to a block of memory such as a cache line while one device has exclusive permission to modify that block of memory. By doing so, a device that has permission to modify may make updates to its copy of the block of memory without invalidating other copies of the block of memory, and potentially enabling other devices to continue to read data from their respective copies of the block of memory without having to retrieve the updated copy of the block of memory.
