Efficient divide and accumulate instruction when an operand is equal to or near a power of two

A method comprising:

• receiving an instruction, which indicates a first source operand and a second source operand;
• determining whether a first data element from the first source operand is equal to a power of two or near the power of two;
• shifting, in response to determining that the first data element is equal to the power of two or near the power of two, a second data element from the second source operand based on the power of two to produce a quotient data element;
• and
• dividing, in response to determining that the first data element is neither equal to the power of two or near the power of two, the first data element with the second data element to produce the quotient data element.

A non-transitory machine-readable medium having program code stored thereon which, when executed by a machine, causes the machine to perform the operations of:

• receiving an instruction, which indicates a first source operand and a second source operand;
• determining whether a first data element from the first source operand is equal to a power of two or near the power of two;
• shifting, in response to determining that the first data element is equal to the power of two or near the power of two, a second data element from the second source operand based on the power of two to produce a quotient data element;
• and
• dividing, in response to determining that the first data element is neither equal to the power of two or near the power of two, the first data element with the second data element to produce the quotient data element.
