摘要： Instructions and logic provide vector load-op and/or store-op with stride functionality. Some embodiments, responsive to an instruction specifying: a set of loads, a second operation, destination register, operand register, memory address, and stride length; execution units read values in a mask register, wherein fields in the mask register correspond to stride-length multiples from the memory address to data elements in memory. A first mask value indicates the element has not been loaded from memory and a second value indicates that the element does not need to be, or has already been loaded. For each having the first value, the data element is loaded from memory into the corresponding destination register location, and the corresponding value in the mask register is changed to the second value. Then the second operation is performed using corresponding data in the destination and operand registers to generate results. The instruction may be restarted after faults.

摘要： Systems, methods, and apparatuses for fault tolerance and detection are described. For example, an apparatus including circuitry to replicate input sources of an instruction; arithmetic logic unit (ALU) circuitry to execute the instruction with replicated input sources using single instruction, multiple data (SIMD) hardware to produce a packed data result; and comparison circuitry coupled to the ALU circuitry to evaluate the packed data result and output a singular data result into a destination of the instruction is described.

A first mask value indicates the element has not been loaded from memory and a second value indicates that the element does not need to be, or has already been loaded.

These instructions can restart after faults.

摘要： A processor core that includes a hardware decode unit to decode a vector frequency compress instruction that includes a source operand and a destination operand. The source operand specifying a source vector register that includes a plurality of source data elements including one or more runs of identical data elements that are each to be compressed in a destination vector register as a value and run length pair. The destination operand identifies the destination vector register. The processor core also includes an execution engine unit to execute the decoded vector frequency compress instruction which causes, for each source data element, a value to be copied into the destination vector register to indicate that source data element's value. One or more runs of the source data elements equal are encoded in the destination vector register as the predetermined compression value followed by a run length for that run.

摘要： Instructions and logic provide vector scatter-op and/or gather-op functionality. In some embodiments, responsive to an instruction specifying: a gather and a second operation, a destination register, an operand register, and a memory address; execution units read values in a mask register, wherein fields in the mask register correspond to offset indices in the indices register for data elements in memory. A first mask value indicates the element has not been gathered from memory and a second value indicates that the element does not need to be, or has already been gathered. For each having the first value, the data element is gathered from memory into the corresponding destination register location, and the corresponding value in the mask register is changed to the second value. When all mask register fields have the second value, the second operation is performed using corresponding data in the destination and operand registers to generate results.
