摘要： An apparatus and method are described for real time instruction tracing. For example, a method according to one embodiment comprises: recording user specified address ranges for which tracing is required; monitoring a next linear instruction pointer (NLIP) values and/or branch linear instruction pointer (BLIP) values to determine if address range has been entered; when the range is entered, compressing the NLIP and/or BLIP values and constructing fixed length packets containing the tracing data; and transferring the fixed length packets to a memory execution cluster.

摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing optional logging of debug activities in a real time instruction tracing log. For example, in one embodiment, such means may include an integrated circuit having means for initiating instruction tracing for instructions of a traced application, mode, or code region, as the instructions are executed by the integrated circuit; means for generating a plurality of packets to a debug log describing the instruction tracing; means for initiating an alternative mode of execution within the integrated circuit; and means for suppressing indication of entering the alternative mode of execution. Additional and alternative means may be implemented for selectively causing an integrated circuit to operate in accordance with an invisible trace mode or a visible trace mode upon transition to the alternative mode of execution.

摘要： Method, apparatus, and program means for performing a packed multiply high with round and shift operation. The method of one embodiment comprises receiving a first operand having a first set of L data elements. A second operand having a second set of L data elements is received. L pairs of data elements are multiplied together to generate a set of L products. Each of the L pairs includes a first data element from the first set of L data element and a second data element from a corresponding data element position of the second set of L data elements. Each of the L products are rounded to generate L rounded values. Each of said L rounded values are scaled to generate L scaled values. Each of the L scaled values are truncated for storage at a destination. Each truncated value is to be stored at a data element position corresponding to its pair of data elements.

摘要： A computer system and processor for elimination of move operations include circuits that obtain a computer instruction and bypass execution units in response to determining that the instruction includes a move operation that involves a transfer of data from a logical source register to a logical destination register. Instead of executing the move operation, the transfer of the data is performed by tracking changes in data dependencies of the source and the destination registers, and assigning a physical register associated with the source register to the destination register based on the dependencies.
