Interruptible and restartable matrix multiplication instructions, processors, methods, and systems

A non-transitory machine readable medium storing an instance of an instruction which when processed by a processor is to cause a method to be performed, the method comprising:

• decoding the instruction, the instruction to indicate a first location of a first source matrix, to indicate a second location of a second source matrix, and to indicate a third location where a result matrix is to be stored;
• and
• in response to the decoded instruction:
• breaking the first source matrix into a plurality of non-overlapping matrices and breaking the second source matrix into a plurality of non-overlapping matrices;
• performing operations on the plurality of non-overlapping matrices from the first source matrix and the plurality of non-overlapping matrices from the second source matrix to generate the result matrix;
• and
• storing the result matrix in the third location.

A method comprising:

• decoding an instruction, the instruction indicating a first location of a first source matrix, indicating a second location of a second source matrix, and indicating a third location where a result matrix is to be stored;
• and
• performing operations corresponding to the instruction, including:
• breaking the first source matrix into a plurality of non-overlapping matrices;
• breaking the second source matrix into a plurality of non-overlapping matrices;
• performing operations on the plurality of non-overlapping matrices from the first source matrix and the plurality of non-overlapping matrices from the second source matrix to generate the result matrix;
• and
• storing the result matrix in the third location.
