  • Publication number: 20130166884
    Abstract: A method and apparatus for including in a processor instructions for performing logical-comparison and branch support operations on packed or unpacked data. In one embodiment, instruction decode logic decodes instructions for an execution unit to operate on packed data elements including logical comparisons. A register file including 128-bit packed data registers stores packed single-precision floating point (SPFP) and packed integer data elements. The logical comparisons may include comparison of SPFP data elements and comparison of integer data elements and setting at least one bit to indicate the results. Based on these comparisons, branch support actions are taken. Such branch support actions may include setting the at least one bit, which in turn may be utilized by a branching unit in response to a branch instruction. Alternatively, the branch support actions may include branching to an indicated target code location.

  • Patent number: 8380780
    Abstract: A method and apparatus for including in a processor instructions for performing logical-comparison and branch support operations on packed or unpacked data. In one embodiment, a processor is coupled to a memory. The memory has stored therein a first data and a second data. The processor performs logical comparisons on the first and second data. The logical comparisons may be performed on each bit of the first and second data, or may be performed only on certain bits. For at least one embodiment, at least the first data includes packed data elements, and the logical comparisons are performed on the most significant bits of the packed data elements. The logical comparisons may include comparison of the same respective bits of the first and second data, and also includes logical comparisons of bits of the first data with the complement of the corresponding bits of the second data. Based on these comparisons, branch support actions are taken.

  • Publication number: 20070150653
    Abstract: According to one embodiment of the invention, a method is disclosed for receiving a request for cacheable memory type data in a cache-controller in communication with a first cache memory; obtaining the requested data from a first memory device in communication with the first cache memory if the requested data does not resides in at least one of the cache-controller and the first cache memory; allocating a data storage buffer in the cache-controller for storage of the obtained data; and setting the allocated data storage buffer to a streaming data mode if the obtained data is a streaming data to prevent an unrestricted placement of the obtained streaming data into the first cache memory.

  • Publication number: 20050219252
    Abstract: A buffer logic within a memory module having the capability to carry out a test of another memory module to which it is coupled via a point-to-point bus through autonomously storing and transmitting a test pattern across that point-to-point bus to the other memory module, while further employing another buffer logic that is interposed between the two memory modules to pass on the test pattern, but intercept a signal received from the other memory module during the test and pass on an indication of the receipt of that signal to an analysis device to monitor the test.
