Abstract: A processor configured to provide instructions of a first instruction type to a first execution unit, and a second execution queue configured to provide instructions of a second instruction type to a second execution unit. A first instruction of the second instruction type is received. The first instruction is decoded by the decode/issue unit to determine operands of the first instruction. The operands of the first instruction are determined to include a dependency on a second instruction of the first instruction type stored in a first entry of the first execution queue. The first instruction is stored in a first entry of the second execution queue. A synchronization indicator corresponding to the first instruction in a second entry of the first execution queue is set immediately adjacent the first entry of the first execution queue, which indicates that the first instruction is stored in another execution queue.

Abstract: Processing systems and methods are disclosed that can include an instruction unit which provides instructions for execution by the processor; a decode/issue unit which decodes instructions received from the instruction unit and issues the instructions; and a plurality of execution queues coupled to the decode/issue unit, wherein each issued instruction from the decode/issue unit can be stored into an entry of at least one queue of the plurality of execution queues. The plurality of queues can comprise an independent execution queue, a dependent execution queue, and a plurality of execution units coupled to receive instructions for execution from the plurality of execution queues. The plurality of execution units can comprise a first execution unit, coupled to receive instructions from the dependent execution queue and the independent execution queue which have been selected for execution.

Abstract: Systems and methods are disclosed that can include a processor having an instruction unit, a decode/issue unit, a first execution queue configured to provide instructions of a first instruction type to a first execution unit, and a second execution queue configured to provide instructions of a second instruction type to a second execution unit. A first instruction (IMUL) of the second instruction type is received. The first instruction is decoded by the decode/issue unit to determine operands of the first instruction. The operands of the first instruction are determined to include a dependency on a second instruction (Id) of the first instruction type stored in a first entry of the first execution queue. The first instruction is stored in a first entry of the second execution queue.
