  • PROCESSING UNIT, CHIP, COMPUTING DEVICE AND METHOD FOR ACCELERATING DATA TRANSMISSION
    Publication number: 20110246667
    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.

  • FAST CONTEXT SAVE IN TRANSACTIONAL MEMORY
    Publication number: 20100217945
    Abstract: The present invention provides a method, apparatus and article of manufacture, for fast context saving in transactional memory. The method creates a mapping table that includes entries corresponding to architectural registers. Each entry includes a physical register index and shadow bit of a first physical register mapped to an architectural register. In response to a detection that an update occurs to an architectural register in a transaction and its shadow bit being an invalid value, the method sets the shadow bit to be a valid value and sets a shadow register for the architectural register using the physical register index of the first physical register. The method maps a second physical register to the shadow register in order to save a modified value generated by an update process and saves the original value before the update process by use of the first physical register corresponding to the architecture register.
