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： The inventive system and method allows for software control of hardware drral of exceptions in speculative operations, and comprises three components. The first component is processor stored information which reflects the code generation strategy of applications and is used by hardware and the operating system to control exception deferral. The second component is processor stored information set by the operating system to specify to hardware which type of faults should be automatically deferred. The third component is further processor stored information which indicates to the hardware to defer certain exception causing aspects of the speculative operation, while performing other non excepting aspects of the speculative operation. The stored information is set after the operating system exception handler has unsuccessfully attempted fault resolution.

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 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 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： 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.
摘要翻译：本发明涉及包含虚拟存储器的计算机系统的设计，其中虚拟页码长于设计的计算机系统的固有基本数据宽度。代替在页表条目中存储整个标签，而不是存储缩小的标签。缩小标签的大小的长度不应大于基本计算机数据宽度，因此单个比较操作将确定缩小的标签与存储在页表条目中的标签之间是否存在匹配。为了保持页表项的唯一性，使用从虚拟地址中删除以形成缩减标记的任何位来形成页表中的索引。

摘要： A multiprocessor computer system comprises multiple data processors, each with an internal clock for providing time stamps to application software. The processors take turns as synchronization masters. The present master transmits a “request” time stamp (indicating the time of transmission according to the local clock) to the other (“slave”) processors. Each slave processor responds by returning a “response” time stamp (indicating the time of transmission of the response according to the local slave clock) of its own along with the received request time stamp. The master calculates clock adjustment values from the time of receipt of the responses and the included time stamps. This allows asynchronous clocks to be synchronized so that application time stamps can be validly compared across processors.

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.
