Die of Intel i860 XP.. The first implementation of the i860 architecture is the i860 XR microprocessor (code-named N10), which ran at 25, 33, or 40 MHz.The second-generation i860 XP microprocessor (code named N11) added 4 Mbyte pages, larger on-chip caches, second level cache support, faster buses, and hardware support for bus snooping, for cache consistency in multiprocessor systems.
i860 may refer to: Intel i860, a VLIW RISC microprocessor; Intel 860 Chipset; Motorola i860, a mobile phone; See also. 1860 This page was last edited on 29 ...
An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.
The DMI bus is visible between CPU and PCH. DMI is essentially PCI Express, using multiple lanes and differential signaling to form a point-to-point link. Most implementations use a ×8 or ×4 link, while some mobile systems (e.g. 915GMS, 945GMS/GSE/GU and the Atom N450) use a ×2 link, halving the bandwidth. The original implementation ...
A front-side bus using a variant of Gunning transceiver logic to enable four discrete processors to share system resources. [4] Physical Address Extension (PAE) and a wider 36-bit address bus to support 64 GB of physical memory. [5] Register renaming, which enabled more efficient execution of multiple instructions in the pipeline.
