    9/11/2014В В· Techniques are addressed for parallel dispatch of coprocessor and thread instructions to a coprocessor coupled to a threaded processor. A first packet of threaded processor instructions is accessed from an instruction fetch queue (IFQ) and a second packet of coprocessor instructions is accessed from the IFQ. A configurable coprocessor interface between a central processing unit (CPU) and a coprocessor is provided. The interface groups signals that together comprises all the necessary information for a coprocessor to issue and execute instructions. Multiple issue groups are formed where each group supports different types of instructions, such as arithmetic instructions, or data transfer instructions.
