Predicate Vector Pack and Unpack Instructions

A method comprising a processor executing a first instruction defined in an instruction set architecture implemented by the processor, wherein the executing comprises:

• generating a result predicate for a destination predicate register of the first instruction responsive to at least one source predicate from a source predicate register of the first instruction;
• and
• generating a result attribute for the destination predicate register as a function of a source attribute of the source predicate register.

A processor comprising:

• a register file comprising a plurality of vector registers and a plurality of predicate registers, wherein each predicate register stores an attribute and a plurality of predicates during use, and wherein each vector register stores a vector during use, each vector have a plurality of vector elements;
• and
• an execution core coupled to the register file, wherein the execution core is configured to execute a first instruction to generate a result vector as a function of at least one source vector from a source vector register of the first instruction and wherein the operation of the function is based on a source attribute from a source predicate register of the first instruction.
