摘要： Methods and apparatus are disclosed using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode scatter/gather instructions and generate micro-operations. An index array holds a set of indices and a corresponding set of mask elements. A finite state machine facilitates the scatter operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. Storage is allocated in a buffer for each of the set of addresses being generated. Data elements corresponding to the set of addresses being generated are copied to the buffer. Addresses from the set are accessed to store data elements if a corresponding mask element has said first value and the mask element is changed to a second value responsive to completion of their respective stores.

摘要： An apparatus and method are described for efficiently transferring data from a core of a central processing unit (CPU) to a graphics processing unit (GPU). For example, one embodiment of a method comprises: writing data to a buffer within the core of the CPU until a designated amount of data has been written; upon detecting that the designated amount of data has been written, responsively generating an eviction cycle, the eviction cycle causing the data to be transferred from the buffer to a cache accessible by both the core and the GPU; setting an indication to indicate to the GPU that data is available in the cache; and upon the GPU detecting the indication, providing the data to the GPU from the cache upon receipt of a read signal from the GPU.

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.

摘要： A method of an aspect includes receiving a floating point rounding instruction. The floating point rounding instruction indicates a source of one or more floating point data elements, indicates a number of fraction bits after a radix point that each of the one or more floating point data elements are to be rounded to, and indicates a destination storage location. A result is stored in the destination storage location in response to the floating point rounding instruction. The result includes one or more rounded result floating point data elements. Each of the one or more rounded result floating point data elements includes one of the floating point data elements of the source, in a corresponding position, which has been rounded to the indicated number of fraction bits. Other methods, apparatus, systems, and instructions are disclosed.
