    Very long pipeline. The Prescott was a major architectural revision. Later revisions were the first to feature Intel's x86-64 architecture, enhanced branch prediction and trace cache, and eventually support was added for the NX (No eXecute) bit to implement executable-space protection.

  3. Prefetch input queue - Wikipedia

    en.wikipedia.org/wiki/Prefetch_input_queue

    The 8086 processor has a six-byte prefetch instruction pipeline, while the 8088 has a four-byte prefetch. As the Execution Unit is executing the current instruction, the bus interface unit reads up to six (or four) bytes of opcodes in advance from the memory. The queue lengths were chosen based on simulation studies. [9]

  4. Intel 8086 - Wikipedia

    en.wikipedia.org/wiki/Intel_8086

    The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.

  5. Instruction pipelining - Wikipedia

    en.wikipedia.org/wiki/Instruction_pipelining

    In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...

    en.wikipedia.org/wiki/X86

    An 8086 system, including coprocessors such as 8087 and 8089, and simpler Intel-specific system chips, [d] was thereby described as an iAPX 86 system. [7] [e] There were also terms iRMX (for operating systems), iSBC (for single-board computers), and iSBX (for multimodule boards based on the 8086-architecture), all together under the heading ...

  7. Pipeline (computing) - Wikipedia

    en.wikipedia.org/wiki/Pipeline_(computing)

    In computing, a pipeline or data pipeline [1] is a set of data processing elements connected in series, where the output of one element is the input of the next one. The elements of a pipeline are often executed in parallel or in time-sliced fashion. Some amount of buffer storage is often inserted between elements. Computer-related pipelines ...

    en.wikipedia.org/wiki/Service_Portfolio_(ITIL)

    The Service Portfolio is described in the ITIL books Service Strategy and Service Design. [1] The Service Portfolio is the core repository for all information for all services in an organization. Each service is listed along with its current status and history. The main descriptor in the Service Portfolio is the Service Design Package (SDP). [2]
