Vector index instruction for processing vectors

A processor that generates a result vector with N elements, comprising:

• an execution unit, wherein the execution unit is configured to:
• receive a start value, and an increment value, and optionally receive a predicate vector, wherein the predicate vector includes N elements;
• and
• generate the result vector, wherein generating the result vector comprises, when the predicate vector is received, for each element in the result vector for which a corresponding element of the predicate vector is active, otherwise, for each element in the result vector,
• setting the element in the result vector equal to the start value plus a product of the increment value multiplied by a specified number of elements to the left of the element in the result vector.

A computer system that generates a result vector with N elements, comprising:

• a processor;
• a memory coupled to the processor, wherein the memory stores instructions and data for the processor;
• and
• an execution unit in the processor, wherein the execution unit is configured to:
• receive a start value, and an increment value, and optionally receive a predicate vector, wherein the predicate vector includes N elements;
• and
• generate the result vector, wherein generating the result vector comprises, when the predicate vector is received, for each element in the result vector for which a corresponding element of the predicate vector is active, otherwise, for each element in the result vector,
• setting the element in the result vector equal to the start value plus a product of the increment value multiplied by a specified number of elements to the left of the element in the result vector.
