20090172344 | METHOD, SYSTEM, AND APPARATUS FOR PAGE SIZING EXTENSION - A method, system, and apparatus may initialize a fixed plurality of page table entries for a fixed plurality of pages in memory, each page having a first size, wherein a linear address for each page table entry corresponds to a physical address and the fixed plurality of pages are aligned. A bit in each of the page table entries for the aligned pages may be set to indicate whether or not the fixed plurality of pages is to be treated as one combined page having a second page size larger than the first page size. Other embodiments are described and claimed. | 07-02-2009 |
20100042779 | Implementing Vector Memory Operations - In one embodiment, the present invention includes an apparatus having a register file to store vector data, an address generator coupled to the register file to generate addresses for a vector memory operation, and a controller to generate an output slice from one or more slices each including multiple addresses, where the output slice includes addresses each corresponding to a separately addressable portion of a memory. Other embodiments are described and claimed. | 02-18-2010 |
20100332801 | Adaptively Handling Remote Atomic Execution - In one embodiment, a method includes receiving an instruction for decoding in a processor core and dynamically handling the instruction with one of multiple behaviors based on whether contention is predicted. If no contention is predicted, the instruction is executed in the core, and if contention is predicted data associated with the instruction is marshaled and sent to a selected remote agent for execution. Other embodiments are described and claimed. | 12-30-2010 |
20130036268 | Implementing Vector Memory Operations - In one embodiment, the present invention includes an apparatus having a register file to store vector data, an address generator coupled to the register file to generate addresses for a vector memory operation, and a controller to generate an output slice from one or more slices each including multiple addresses, where the output slice includes addresses each corresponding to a separately addressable portion of a memory. Other embodiments are described and claimed. | 02-07-2013 |
20130117531 | METHOD, SYSTEM, AND APPARATUS FOR PAGE SIZING EXTENSION - A method, system, and apparatus may initialize a fixed plurality of page table entries for a fixed plurality of pages in memory, each page having a first size, wherein a linear address for each page table entry corresponds to a physical address and the fixed plurality of pages are aligned. A bit in each of the page table entries for the aligned pages may be set to indicate whether or not the fixed plurality of pages is to be treated as one combined page having a second page size larger than the first page size. Other embodiments are described and claimed. | 05-09-2013 |
20130262771 | INDICATING A LENGTH OF AN INSTRUCTION OF A VARIABLE LENGTH INSTRUCTION SET - Some implementations disclosed herein provide techniques and arrangements for indicating a length of an instruction from an instruction set that has variable length instructions. A plurality of bytes that include an instruction may be read from an instruction cache based on a logical instruction pointer. A determination is made whether a first byte of the plurality of bytes identifies a length of the instruction. In response to detecting that the first byte of the plurality of bytes identifies the length of the instruction, the instruction is read from the plurality of bytes based on the length of the instruction. | 10-03-2013 |
20140052968 | SUPER MULTIPLY ADD (SUPER MADD) INSTRUCTION - A method of processing an instruction is described that includes fetching and decoding the instruction. The instruction has separate destination address, first operand source address and second operand source address components. The first operand source address identifies a location of a first mask pattern in mask register space. The second operand source address identifies a location of a second mask pattern in the mask register space. The method further includes fetching the first mask pattern from the mask register space; fetching the second mask pattern from the mask register space; merging the first and second mask patterns into a merged mask pattern; and, storing the merged mask pattern at a storage location identified by the destination address. | 02-20-2014 |
20150277904 | METHOD AND APPARATUS FOR PERFORMING A PLURALITY OF MULTIPLICATION OPERATIONS - An apparatus and method are described for performing a plurality of multiplication operations. For example, one embodiment of a processor comprises an instruction fetch unit to fetch a double-multiplication instruction from a memory subsystem, the double-multiplication instruction having three source operand values; a decode unit to decode the double-multiplication instruction to generate at least one uop; and an execution unit to execute the uop a first time to multiply a first and a second of the three source operand values to generate a first intermediate result and to execute the uop a second time to multiply the intermediate result with a third of the three source operand values to generate a final result. | 10-01-2015 |
