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.
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
Bus systems such as the SATA ports in modern computers support multiple peripherals, allowing multiple hard drives to be connected without an expansion card. In systems that have a similar architecture to multicomputers, but which communicate by buses instead of networks, the system bus is known as a front-side bus.

The standard Multibus form factor was a 12-inch-wide (300 mm), 6.75-inch-deep (171 mm) circuit board with two ejection levers on the front edge. The board had two buses: a wider P1 bus with pin assignment defined by the Multibus specification and a second smaller P2 bus was also defined as a private bus.
NeXT offered a 68040 system board upgrade (and NeXTSTEP 2.0) for US$1,495 (equivalent to $3,490 in 2023). A 33 MHz NeXTcube Turbo was later produced. NeXT released the NeXTdimension for the NeXTcube, a circuit board based on an Intel i860 processor, which offers 32-bit PostScript color display and video-sampling features.
The Paragon XP/S is a productized version of the experimental Touchstone Delta system that was built at Caltech, launched in 1992. The Paragon superseded Intel's earlier iPSC/860 system, to which it is closely related. The Paragon series is based on the Intel i860 RISC microprocessor. Up to 2048 (later, up to 4096) i860s are connected in a 2D grid.
In original system designs, LAPICs and I/O APICs were connected by a dedicated APIC bus. Newer systems use the system bus for communication between all APIC components. Each APIC, whether a discrete chip or integrated in a CPU, has a version register containing a four-bit version number for its specific APIC implementation.
