parallel interface

[′par·ə‚lel ′in·tər‚fās]
(electronics)
A link between two devices in which all the information transferred between them is transmitted simultaneously over separate conductors. Also known as parallel port.

parallel interface

A multiline channel that transfers one or more bytes simultaneously. For years, desktop and laptop computers were connected to printers via a 36-wire parallel interface, transferring a byte of data over eight wires, the remaining wires used for control signals. The parallel interface gave way to a serial interface. See parallel cable, parallel port and serial interface.

While the xSil267 controls serial-only, multi-slot applications such as those where Secure Digital (SD), Multimedia Card (MMC), and Memory Stick (MS) media interface with a PC Express Card adapter or USB Host, the xSil268 controls both serial and parallel interfaces for multi-slot applications enabling it to read from a wide range of media formats including UDMA CompactFlash (CF), MMC 4.
Because of the inherent physical limitations of parallel interfaces, inexpensive or cost-effective serial interfaces like 10- and 40-Gigabit Ethernet, SATA and 3GIO (PCI Express) are poised to be part of this flourishing future for IP storage.
For high bandwidth switch fabrics, these parallel interfaces cannot run across the backplane due to signal density limitations.
