Abstract: A tag monitoring system for assigning tags to instructions. A source supplies instructions to be executed by a functional unit. A register file stores information required for the execution of each instruction. A queue having a plurality of slots containing tags which are used for tagging the instructions. The tags are arranged in the queue in an order specified by the program order of their corresponding instructions. A control unit monitors the completion of executed instructions and advances the tags in the queue upon completion of an executed instruction. The register file stores an instruction's information at a location in the register file defined by the tag assigned to that instruction. The register file also contains a plurality of read address enable ports and corresponding read output ports. Each of the slots from the queue is coupled to a corresponding one of the read address enable ports. Thus, the information for each instruction can be read out of the register file in program order.

Abstract: An system and method for retiring instructions in a superscalar microprocessor which executes a program comprising a set of instructions having a predetermined program order, the retirement system for simultaneously retiring groups of instructions executed in or out of order by the microprocessor. The retirement system comprises a done block for monitoring the status of the instructions to determine which instruction or group of instructions have been executed, a retirement control block for determining whether each executed instruction is retirable, a temporary buffer for storing results of instructions executed out of program order, and a register array for storing retirable-instruction results.

Abstract: An intelligent memory system, method, and computer program product for enabling stand-alone or distributed client-server software applications to operate at maximum speeds on a personal computer and the like. An intelligent memory allows the acceleration of computer software processes through process virtual memory, application optimization, multiprocessor control, and system strategies. The intelligent memory includes both control logic and memory. The control logic uses an application database and system database to determine a set of modifications to the computer, application, and/or operating system, while the memory stores the application and allows the control logic to implement the set of modifications.

Abstract: A system and method for performing register renaming of source registers in a processor having a variable advance instruction window for storing a group of instructions to be executed by the processor, wherein a new instruction is added to the variable advance instruction window when a location becomes available. A tag is assigned to each instruction in the variable advance instruction window. The tag of each instruction to leave the window is assigned to the next new instruction to be added to it. The results of instructions executed by the processor are stored in a temp buffer according to their corresponding tags to avoid output and anti-dependencies. The temp buffer therefore permits the processor to execute instructions out of order and in parallel. Data dependency checks for input dependencies are performed only for each new instruction added to the variable advance instruction window and register renaming is performed to avoid input dependencies.

Abstract: An intelligent memory system, method, and computer program product for enabling stand-alone or distributed client-server software applications to operate at maximum speeds on a personal computer and the like. An intelligent memory (IM) allows the acceleration of computer software processes through process virtual memory, application optimization, multiprocessor control, and system strategies. The IM includes both control logic and memory. The control logic uses an application database and system database to determine a set of modifications to the computer, application, and/or operating system, while the memory stores the application and allows the control logic to implement the set of modifications. A remote performance management system is also described which allows an IM service provider to supply the infrastructure to clients (e.g., e-businesses and the like who run World Wide Web servers) to facilitate and accelerate their content offerings to end user clients (i.e., consumers).
