In an age of multigabit-per-second serial interconnects, logic analyzers may seem to be relics of a bygone era in which parallel buses were king. “Not so,” say engineers who have logged many hours ...

Standard parallel-bus structures are reaching their performance limits. The only way to increase system bandwidth is to switch to a serial-bus structure. Although serial structures promise enhanced ...

Those have a length that’s defined by the width of the bus. In the case of PCIe, there is no bus, so instead we get the ‘core’ connector pin-out with a single lane (x1 connector).

As processor clock speeds increase, parallel buses such as PCI become harder to implement. Signal skew and fan-out restrictions restrict the bandwidth achievable on a parallel bus.

The bus in a PC is the common hardware interface between the CPU and peripheral devices. Parallel buses with multiple lines (wires) were superseded by serial versions, which use one line for data.

Parallel buses are giving way to high-speed serial/pseudoserial buses, especially in I/Os and system interconnects. Buses like PCI and PCI-X, the universal PC I/O and embedded ...

StarFabric provides a simple migration path from existing open platform architectures that are based on a parallel bus architecture. It is 100% backward compatible with PCI, H.110 and Utopia.

The I/O bus from the CPU to the peripherals is a parallel bus (16, 32 or 64 wires, etc.). Serial Bus vs. Serial Port Although sounding similar, a serial bus differs from a serial port.

It’s a physical layer interface for wired communications that uses a single differential pair for noise immunity, has good long-distance properties, and allows many connections to a single bus.

The bus situation inside of systems is getting a lot better here in 2019. The PCI-Express 4.0 bus, which was introduced in 2017, came out first in IBM’s Power9-based Power Systems machines later that ...
