Scalable matrix node engine with configurable data formats

A microprocessor system, comprising:

• a matrix processor, wherein the matrix processor is configured to receive a matrix processor instruction that specifies a floating-point operand formatted with an exponent that has been biased with a specified bias;
• a post-processing unit;
• a control unit configured to provide a post-processing instruction to the post-processing unit and the matrix processor instruction to the matrix processor;
• and
• a post-processing register file, wherein the post-processing instruction specifies an operand stored in the post-processing register file.

A method comprising:

• receiving a matrix processor instruction from a control unit, wherein the matrix processor instruction specifies a floating-point operand formatted with an exponent that has been biased with a specified bias;
• issuing one or more reads for data values of the floating-point operand;
• receiving the data values of the floating-point operand;
• and
• loading one or more received data values into a matrix computational unit.

A method comprising:

• receiving a matrix processor instruction from a control unit, wherein the matrix processor instruction specifies a first floating-point operand and a second floating-point operand;
• loading a first half of the first floating-point operand into a first processing element and a second processing element;
• loading a second half of the first floating-point operand into a third processing element and a fourth processing element;
• loading a first half of the second floating-point operand into the first processing element and the third processing element;
• loading a second half of the second floating-point operand into the second processing element and the fourth processing element;
• determining a first, second, third, and fourth floating-point multiplication result corresponding to each of the first, second, third, and fourth processing elements;
• and
• storing the first, second, third, and fourth floating-point multiplication result in an output accumulator.
