Processors, methods, systems, and instructions to select and store data elements from two source two-dimensional arrays indicated by permute control elements in a result two-dimensional array

A method performed by a processor comprising:

• decoding an instruction having an opcode, the instruction indicating a first source two-dimensional (2D) array of data elements arranged in a plurality of rows and a plurality of columns, a second source 2D array of data elements arranged in a plurality of rows and a plurality of columns, and a plurality of permute control elements;
• and
• performing operations corresponding to the instruction, including:
• selecting a plurality of single data elements, from among any of the data elements of the first source 2D array of data elements, and any of the data elements of the second source 2D array of data elements, wherein every selected single data element of the selected plurality of single data elements is to be selected by a different corresponding one of the plurality of permute control elements;
• and
• storing the selected plurality of single data elements in a plurality of single data element positions of a result 2D array, each and all of the single data element positions of the result 2D array to correspond to a different one of the plurality of permute control elements.

A system comprising:

• an interconnect;
• a processor coupled with the interconnect, the processor to receive an instruction having an opcode, the instruction to indicate a first source two-dimensional (2D) array of data elements arranged in a plurality of rows and a plurality of columns, a second source 2D array of data elements arranged in a plurality of rows and a plurality of columns, and a plurality of permute control elements, the processor, to perform operations corresponding to the instruction, including to:
• select a plurality of single data elements, from among any of the data elements of the first source 2D array of data elements, and any of the data elements of the second source 2D array of data elements, wherein every selected single data element of the selected plurality of single data elements is to be selected by a different corresponding one of the plurality of permute control elements;
• and
• store the selected plurality of single data elements in a plurality of single data element positions of a result 2D array, each and all of the single data element positions of the result 2D array to correspond to a different one of the plurality of permute control elements;
• and
• a dynamic random access memory (DRAM) coupled with the interconnect.
