摘要： Methods and apparatus are disclosed for accessing multiple data cache lines for scatter/gather operations. Embodiment of apparatus may comprise address generation logic to generate an address from an index of a set of indices for each of a set of corresponding mask elements having a first value. Line or bank match ordering logic matches addresses in the same cache line or different banks, and orders an access sequence to permit a group of addresses in multiple cache lines and different banks. Address selection logic directs the group of addresses to corresponding different banks in a cache to access data elements in multiple cache lines corresponding to the group of addresses in a single access cycle. A disassembly/reassembly buffer orders the data elements according to their respective bank/register positions, and a gather/scatter finite state machine changes the values of corresponding mask elements from the first value to a second value.

摘要： A method of an aspect includes receiving an instruction indicating a first source packed memory indices, a second source packed data operation mask, and a destination storage location. Memory indices of the packed memory indices are compared with one another. One or more sets of duplicate memory indices are identified. Data corresponding to each set of duplicate memory indices is loaded only once. The loaded data corresponding to each set of duplicate memory indices is replicated for each of the duplicate memory indices in the set. A packed data result in the destination storage location in response to the instruction. The packed data result includes data elements from memory locations that are indicated by corresponding memory indices of the packed memory indices when not blocked by corresponding elements of the packed data operation mask.
