Patent ID: 8762603

Claim:
A data transmission system, comprising: a receiver associated with a data destination entity; a device for managing transmission of data words between a data source entity and the data destination entity, the device comprising: a write interface configured to receive data words from the data source entity; a read interface configured to forward data words to the data destination entity; a buffer memory configured to temporarily store data words to be transmitted from the write interface to the read interface, wherein the data words are stored in an order in which they are received from the write interface; wherein data words in the buffer memory are addressable for reading at least a part of a data word in such a way that the corresponding data word remains stored in the buffer memory after reading; wherein the receiver is configured to: cause at least part of a first data word to be read from the buffer memory via the read interface; determine whether the first data word should be processed now or later; in response to determining that the first data word read from the buffer memory should be processed later: cause a different second data word to be read from the buffer memory; thereafter, both cause the first data word to be read from the buffer memory and process the first data word; thereafter, send an invalidation command to the buffer memory instructing the buffer memory to delete the first data word; wherein the first data word remains in the buffer memory until receipt of the invalidation command by the buffer memory.
