    摘要: The foam tube for pipe insulations has an external surface and an internal surface. The internal surface is provided with an adhesively bonded layer of fibers. The fibers are a material having a melt temperature that is higher than that of the polymeric foam. The fibers are adhesively bonded to the internal surface such as to stand up from the internal surface. The fibers are substantially uniformly distributed over the internal surface providing a surface coverage of 2 to 20 percent. Further, the fibers have a linear density of 0.5 to 25 dtex and a length of 0.2 to 5 mm. With this fiber layer the polymeric foam tube has an improved thermal resistance and thermal conductivity.

    摘要: A single test access port, such as a JTAG-based debug port may be utilized to perform debug operations on logic cores of a multi-core integrated circuit, such as a multi-core processor. The shared debug port may respond to a particular command to enter a debugging mode and may be configured to forward all commands and data to a debugging controller of the integrated circuit during debugging. A mask register may be used to indicate which logic cores of the multi-core integrated circuit should be debugged. Additionally, custom debugging commands may include mask or core select fields to indicate which logic cores should be affected by the particular command. Debugging mode may be initialized for one or more logic cores either externally, such as be asserted a DBREQ signal, or internally, such as by configuring one or more breakpoints.

    摘要: In one embodiment, a node comprises a plurality of processor cores and a node controller coupled to the processor cores. The node controller is configured to route communications from the processor cores to other devices in a computer system. The node controller comprises a circuit coupled to receive the communications from the processor cores. In a redundant execution mode in which at least a first processor core is redundantly executing code that a second processor core is also executing, the circuit is configured to compare communications from the first processor core to communications from the second processor core to verify correct execution of the code. In some embodiments, the processor cores and the node controller may be integrated onto a single integrated circuit chip as a CMP. A similar method is also contemplated.

    摘要: A method and apparatus for fault handling in computer systems. In one embodiment, a first register is used to store an address which points to the top of a stack. The address stored in the first register may be updated during the execution of an instruction. A second register may be used to store an address previously first register. The contents of the second register may be kept unchanged until the retirement of the instruction that is currently executing. If a fault occurs during execution of the instruction, a microcode fault handler may perform routines that may clear the fault or those conditions which led to the fault. The microcode fault handler may also copy the contents of the second register back into the first register. Execution of the instruction may be restarted from the operation just prior to when the fault occurred. The program from which the instruction originated may then continue to run. The first and second registers may be general purpose registers in some embodiments, while special purpose registers may be used in other embodiments.

    摘要: A method and apparatus for controlling power management state transitions between two devices, e.g., a processor and a bus bridge, that are connected through a clock forwarded interface bus in a computer system. The bus bridge is configured to coordinate disconnection of the processor from the interface. Particularly, the bus bridge may use a fist signal to indicate whether or not the processor is to be disconnected from the interface (e.g. a CONNECT signal) and the processor may use a second signal to indicate whether or not the processor is to be disconnected from the interface (e.g. a PROCREADY signal). The processor is disconnected from the interface responsive to both the first signal and the second signal indicating that the processor is to be disconnected. The signals may also be used to reconnect the processor to the interface.

The fetch program counter circuit provides less significant program counter value bits in addition to a fetch program counter value. The execute program counter circuit generates an execute program counter value using the less significant program counter value bits. The execute program counter circuit receives a plurality of less significant program counter bit values and selects a single less significant program counter bit value thus generating execute program counter values in a multiple pipeline processor.

    摘要: In a processor (110) that performs multiple instructions in a single cycle, predicts outcomes of branch conditions and speculatively executes instructions based on the branch predictions, a method and apparatus for operating a data stack utilize a remap array (674) to support a stack exchange capability. The remap array is used to correlate a stack pointer (672) to data elements (700) within the stack. A lookahead stack pointer (502) and remap array (504) are updated to preserve the processor's state of operation while speculative instructions are executed.

    摘要: A superscalar microprocessor is provided with a reorder buffer for storing the speculative state of the microprocessor and a register file for storing the real state of the microprocessor. A flags register stores the real state of flags that are updated by flag modifying instructions which are executed by the functional units of the microprocessor. To enhance the performance of the microprocessor with respect to conditional branching instructions, the reorder buffer includes a flag storage area for storing flags that are updated by flag modifying instructions. The flags are renamed to make possible the earlier execution of branch instructions which depend on flag modifying instructions. If a flag is not yet determined, then a flag tag is associated with the flag storage area in place of that flag until the actual flag value is determined. A flag operand bus and a flag tag bus are provided between the flag storage area and the branching functional unit so that the requested flag or flag tags are provided to instructions which are executed in the branching functional unit.
