摘要： An extended DRAIN instruction is used to stall processing within a computing environment. The instruction includes an indication of the one or more processing stages at which processing is to be stalled. It also includes a control that allows processing to be stalled for additional cycles, as desired. The enhanced DRAIN instruction enables its use to be more granular and to have minimal impact with respect to each individual use.

摘要： The present invention relates to a method for the unification of PER branch and PER store operations within the same dataflow. The method comprises determining a PER range, the PER range comprising a storage area defined by a designated storage starting area and a designated storage ending area, wherein the storage starting area is designated by a value of the contents of a first control register and the storage ending area is designated by a value of the contents of a second control register. The method also comprises retrieving register field content values that are stored at a plurality of registers, wherein the retrieved content values comprises a length field content value, and setting the length field content value to zero for a PER branch instruction, thereby enabling a PER branch instruction to performed similarly to a PER storage instruction.

摘要： A system and method for overlapping execution (OE) of instructions through non-uniform execution pipelines in an in-order processor are provided. The system includes a first execution unit to perform instruction execution in a first execution pipeline. The system also includes a second execution unit to perform instruction execution in a second execution pipeline, where the second execution pipeline includes a greater number of stages than the first execution pipeline. The system further includes an instruction dispatch unit (IDU), the IDU including OE registers and logic for dispatching an OE-capable instruction to the first execution unit such that the instruction completes execution prior to completing execution of a previously dispatched instruction to the second execution unit. The system additionally includes a latch to hold a result of the execution of the OE-capable instruction until after the second execution unit completes the execution of the previously dispatched instruction.

摘要： A method and system for early instruction text based operand store compare avoidance in a processor are provided. The system includes a processor pipeline for processing instruction text in an instruction stream, where the instruction text includes operand address information. The system also includes delay logic to monitor the instruction stream. The delay logic performs a method that includes detecting a load instruction following a store instruction in the instruction stream, comparing the operand address information of the store instruction with the load instruction. The method also includes delaying the load instruction in the processor pipeline in response to detecting a common field value between the operand address information of the store instruction and the load instruction.
