In order to create these at minimal R&D, engineering and production costs, Novell based their board on the DP839EB, [1] a reference design created by National Semiconductor using the 8390 Ethernet chip. Compared to the reference design's direct memory access, [1] Novell used Programmed I/O, which limited performance.
Multibus I CPU card from a Sun-2 workstation Intel iSBC 386/116 Multibus II Single Board Computer with VLSI A82389 as Multibus Controller. Multibus is a computer bus standard used in industrial systems.
The RapidIO architecture is a high-performance packet-switched electrical connection technology. It supports messaging, read/write and cache coherency semantics. Based on industry-standard electrical specifications such as those for Ethernet, RapidIO can be used as a chip-to-chip, board-to-board, and chassis-to-chassis interconnect.
Amber is an ARM-compatible 32-bit RISC processor. Amber implements the ARMv2 instruction set. LEON, a 32-bit, SPARC-like CPU created by the European Space Agency; OpenPOWER, based on IBM's POWER8 and newer multicore processor designs; OpenSPARC, a series of open-source microprocessors based on the UltraSPARC T1 and UltraSPARC T2 multicore ...
6U cards have an identical J1, a J2 that is always used for 64-bit PCI, as well as J3, J4, and J5 connectors for a variety of uses either as user-defined I/O or specified signaling such as Telephony and/or Ethernet signaling. Hot-plugging is a supported feature of CompactPCI.
Some of the disadvantages of the product were: Though the 80386 was a 32 bit CPU, it was limited to a 16-bit I/O bus in the case of the Intel Inboard 386/AT and an 8-bit I/O bus in the case of the Intel Inboard 386/PC. Both boards retained 32-bit data and address buses, however.
An Ethernet adapter card for the IBM PC was released in 1982, and, by 1985, 3Com had sold 100,000. [16] In the 1980s, IBM's own PC Network product competed with Ethernet for the PC, and through the 1980s, LAN hardware, in general, was not common on PCs. However, in the mid to late 1980s, PC networking did become popular in offices and schools ...
Sercos is a deterministic Ethernet-based automation bus that uses a frame summation technique for highly efficient communication. [7] Cyclic updates to devices are made at rates as low as 31.25 μs [8] Support for up to 511 Slave devices on one network [9] Redundancy: Bump-less physical layer single-fault recovery [10]
