Dispatching a stored instruction in response to determining that a received instruction is of a same instruction type

A subsystem for scheduling instructions for execution, including:

• instruction storage;
• and
• instruction allocation logic coupled to the instruction storage and that:
• receives a first instruction;
• compares the first instruction to a second instruction stored in the instruction storage and determines whether the first instruction is of a different instruction type than the second instruction;
• in response to determining that the first instruction is of a different instruction type than the second instruction:
• identifies a first subset of execution pipelines within a plurality of execution pipelines based on a first set of selection criteria,
• selects a first execution pipeline within the first subset of execution pipelines, wherein the first execution pipeline includes a first execution element that executes the first instruction using less power than other execution elements within other execution pipelines included in the first subset of execution pipelines would use when executing the first instruction, and dispatches the first instruction to the first execution pipeline for execution;
• and
• in response to determining that the first instruction is of a same instruction type as the second instruction:
• dispatches the second instruction for execution within a second execution pipeline selected for the second instruction, wherein the second instruction is dispatched based on determining that the first instruction is of the same instruction type as the second instruction.

A computing device for scheduling instructions for execution, including:

• a memory including instructions;
• and
• a processor coupled to the memory, the processor comprising:
• a plurality of execution pipelines, and
• an instruction scheduling unit that:
• receives a first instruction from the memory;
• compares the first instruction to a second instruction stored in an instruction storage and determines whether the first instruction is of a different instruction type than the second instruction;
• in response to determining that the first instruction is of a different instruction type than the second instruction:
• identifies a first subset of execution pipelines within a plurality of execution pipelines based on a first set of selection criteria,
• selects a first execution pipeline within the first subset of execution pipelines, wherein the first execution pipeline includes a first execution element that executes the first instruction using less power than other execution elements within other execution pipelines included in the first subset of execution pipelines would use when executing the first instruction, and
• dispatches the first instruction to the first execution pipeline for execution;
• and
• in response to determining that the first instruction is of a same instruction type as the second instruction:
• dispatches the second instruction for execution within a second execution pipeline selected for the second instruction, wherein the second instruction is dispatched based on determining that the first instruction is of the same instruction type as the second instruction.
