    摘要: A trace management architecture to enable the reuse of uops within one or more repeated traces. More particularly, embodiments of the invention relate to a technique to prevent multiple accesses to various functional units within a trace management architecture by reusing traces or sequences of traces that are repeated during a period of operation of the microprocessor, avoiding performance gaps due to multiple trace cache accesses and increasing the rate at which uops can be executed within a processor.

    摘要: A system and method of early branch prediction in a processor to evaluate, typically before a full branch prediction is made, ways in a branch target buffer to determine if any of said ways corresponds to a valid unconditional branch, and upon such determination, to generate a signal to prevent a read of a next sequential chunk.

    摘要: Embodiments of the present invention relate to displaying images from memory. A plurality of pixel attributes are retrieved from memory in a single memory transaction. At least one attribute corresponds to one scan line of a display and another attribute corresponds to another scan line of the display. A portion of one scan line using the corresponding pixel attribute is displayed. The pixel attributes corresponding to another scan line is stored in a buffer.

    摘要: An apparatus and method are described for down-converting from a source operand to a destination operand with masking. For example, a method according to one embodiment includes the following operations: reading a source operand value to be down-converted from a first value to a down-converted value and stored in a destination location; reading each mask register bit stored in a mask register, the mask register bit(s) indicating whether to perform a masking operation or a conversion operation on the source operand value; if the mask register bit(s) indicates that a masking operation is to be performed, then performing a specified masking operation and storing the results of the masking operation in the destination location; and if the mask register bit indicates that a masking operation is not to be performed, then down-converting the source operand value and storing the down-converted value in the specified destination location.
