摘要： The present invention relates to the design of computer systems incorporating virtual memory where a virtual page number is longer than the inherent basic data width of the designed computer system. Instead of storing an entire tag in page table entries, a reduced tag is stored. The reduced tag is sized to be no greater in length than the basic computer data width and therefore a single compare operation will ascertain whether there is a match between the reduced tag and the tag stored in a page table entry. To maintain uniqueness of the page table entries, any bits removed from the virtual address to form the reduced tag are used to form an index into the page table.

摘要： A method for operating a digital computer in response to the occurrence of an exception is disclosed. The method provides for the examination both of the contents of a predetermined computer location and of the instruction code for the instruction causing the exception. The computer then utilizes the result of those examinations to determine the dismissibility of the exception. The computer transfers control to the next instruction after the instruction which caused the exception if that instruction is dismissible.

摘要： A method and apparatus for controlling groups of registers includes a pluity of registers of the same type logically separated into a plurality of groups and a plurality of indicators corresponding to the plurality of groups of registers, each of the plurality of indicators identifying whether a corresponding group of registers has been modified by a task currently being executed by the processor. A control logic is also included, coupled to the plurality of registers, to selectively control the plurality of registers by group based at least in part on the plurality of indicators.

摘要： A computer apparatus incorporating special instructions to force load and store operations to execute in program order. The present invention provides a new and novel store instruction that is suspended until all prior store instructions have been completed by an associated CPU. Also, a new load instruction is provided which blocks any subsequent load instructions from executing until this load instruction has been completed by an associated CPU. These instructions allow for high efficiency computer systems to be implemented which optimize instruction throughput by executing subsequent instructions while waiting for a prior instruction to complete.

摘要： A method of converting an original code sequence to a modified code sequence where the original code sequence includes a procedure call that is prior to a load instruction that is configured to load a value into one of a first plurality of registers is provided. The method includes inserting an advanced load instruction associated with one of a second plurality of registers into the modified code sequence where the advanced load instruction is configured to cause the value to be loaded into the one of the first plurality of registers. The method also includes inserting the procedure call into the modified code sequence subsequent to the advanced load instruction and inserting a checking instruction associated with the one of the second plurality of registers into the modified code sequence subsequent to the procedure call.

摘要： A computer system includes a processor for executing a program and an interruption handler from a memory. The processor includes an instruction pointer indicating a memory location of a current executing instruction. The processor executes a trampoline check instruction in the program which tests a condition and if the condition is true, causes an interruption and supplies an address displacement. The interruption handler responds to the interruption and restarts execution of the program at a restart point indicating a memory location of a special handler in the program. The restart point is a sum of the address displacement and a value of the instruction pointer at the time of the interruption. If the condition is false, normal control flow of the program is continued.

摘要： A computer apparatus which detects a store or load operation into or from a shared memory page by a program that does not provide for synchronization when executed by a CPU that completes instructions out of program order. After the store or load is detected, the CPU explicitly orders operations into the shared memory page. Store operations are ordered such that no new store into the shared memory page is performed until all prior store operations into the shared memory page are complete. Also, load operations are ordered such that load operations from the shared memory page are performed in program order. This ordering is achieved by maintaining a process bit and a memory attribute bit associated with a shared memory page. When both bits are true, all load or store operations referencing the shared memory page are ordered.

摘要： An event calling for a migration of a workload from a source processor set of processing units to a target processor set of processing units is detected. Processes of the workload are allocated to a second processor set of processing units so that some workload processes are executed on the source processor set and some workload processes are executed on a second processor set of processor units. Then, some workload processes are allocated to the second processor set so that no workload process is executing on the source processor set and at least some of said processes are executing on the second process set. The second processor set can be the target processor set or an intermediate processor set from which the workload is migrated to the target processor set.

摘要： A secure promotion mechanism promotes a current privilege level of a processor in a computer system. The current privilege level controls application instruction execution in the computer system by controlling accessibility to system resources. An operating system performs a privilege promotion instruction, which is stored in a first page of memory not writeable by an application instructions at a first privilege level. The privilege promotion instruction reads a stored previous privilege level state, compares the read previous privilege level state to the current privilege level, and if the previous privilege level state is equal to or less privileged than the current privilege level, promotes the current privilege level to a second privilege level which is higher than the first privilege level.
