z Uses 8b/10b encoding, meaning that 20% of each transfer is used by the interface instead of carrying data from between the hardware components at each end of the interface. For example, a single link PCIe 1.0 has a 2.5 Gbit/s transfer rate, yet its usable bandwidth is only 2 Gbit/s (250 MB/s).
IEEE 1394 is a serial bus architecture for high-speed data transfer, serial meaning that information is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. [6] IEEE 1394 fully supports both isochronous and asynchronous applications.
The bit rate here is a fixed 31.25 kbit/s. This technology was specially established for use in process automation for PROFIBUS PA. [17] For data transfer via sliding contacts for mobile devices or optical or radio data transmission in open spaces, products from various manufacturers can be obtained, however they do not conform to any standard.
In telecommunications, data transfer rate is the average number of bits , characters or symbols , or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s).
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers.
The abstract data models defined in IEC 61850 can be mapped to a number of protocols. Current mappings in the standard are to Manufacturing Message Specification (MMS), GOOSE (Generic Object Oriented System Event) [see section 3, Terms and definitions, term 3.65 on page 14 [ 2 ] ], SV (Sampled Values) or SMV (Sampled Measure Values), [ 3 ] and ...
Serial Front Panel Data Port [1] (Serial FPDP or SFPDP) is a high speed low latency data streaming serial communication protocol. It currently supports several distinct speeds: [ 2 ] 1.0625 Gbit / s
User data bit allocations: [7] User bit 0 is designated for Timecode transport; User bit 1 is designated for MIDI data transport; User bit 2 is designated for S/Mux indication (96 kHz sample rate mode) [8] [9] User bit 3 is reserved and set to 0; The transmission speed of the user bits is equal to the sampling rate (e.g. 48,000 bits per second)
