Abstract
A processing unit coupled to a bus for accelerating data transmission and a method for accelerating data transmission. The present invention provides a streaming data transmission mode in which a plurality of data blocks are transmitted via one handshake. The present invention employs handshake save policy, when a processing unit sends a request comprising a plurality of data blocks on a bus, a cache or memory will perform address matching to judge whether there is any hit data block. If there is any hit data block, the cache or memory only needs to reply once and then start to continuously transmit the hit data blocks it possesses. Thus, a separate handshake for each data block is no longer needed.
