Register sharing mechanism

A method to facilitate register sharing, comprising:

• decoding an instruction including one or more source operands;
• determining whether the one or more source operands are stored in a shared set of registers in a General Purpose Register File (GRF);
• returning addresses of the one or more registers in a dedicated set of registers in the GRF upon a determination that the one or more source operands are stored in the dedicated set of registers;
• and
• requesting acquisition of a group of one or more registers in the shared set of registers upon a determination that the one or more source operands are stored in the shared set of registers.

At least one non-transitory computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:

• decode an instruction including one or more source operands;
• determine whether the one or more source operands are stored in a shared set of registers in a General Purpose Register File (GRF);
• return addresses of the one or more registers in a dedicated set of registers in the GRF upon a determination that the one or more source operands are stored in a dedicated set of registers;
• and
• request acquisition of a group of one or more registers in the shared set of registers upon a determination that the one or more source operands are stored in the shared set of registers.
