For example, the SPD data on an SDRAM module might provide information about the CAS latency so the system can set this correctly without user intervention. The SPD EEPROM firmware is accessed using SMBus, a variant of the I 2 C protocol. This reduces the number of communication pins on the module to just two: a clock signal and a data signal.
ARINC 615 defines a high-speed data loader protocol layered upon the ARINC 429 physical layer. ARINC 629 defines a high-speed, multi-transmitter, TDMA extension to ARINC 429, superseded by AFDX. ARINC 664 Part 7 defines the use of a deterministic Ethernet network as an avionic databus in later aircraft like the Airbus A380 and the Boeing 787 ...
Matrix (sometimes stylized as [matrix]) is an open standard and communication protocol for real-time communication. [2] It aims to make real-time communication work seamlessly between different service providers, in the way that standard Simple Mail Transfer Protocol email currently does for store-and-forward email service, by allowing users with accounts at one communications service provider ...
In its second version, AMBA 2 in 1999, Arm added AMBA High-performance Bus (AHB) that is a single clock-edge protocol. In 2003, Arm introduced the third generation, AMBA 3, including Advanced eXtensible Interface (AXI) to reach even higher performance interconnect and the Advanced Trace Bus (ATB) as part of the CoreSight on-chip debug and trace ...
High-speed CAN 2.0 supports bit rates from 40 kbit/s to 1 Mbit/s and is the basis for higher-layer protocols. In contrast, low-speed CAN 2.0 supports bit rates from 40 kbit/s to 125 kbit/s and offers fault tolerance by allowing communication to continue despite a fault in one of the two wires, with each node maintaining its own termination.
Goals of the MIPI Sensor Working Group effort were first announced in November 2014 at the MEMS Executive Congress in Scottsdale AZ. [8]Electronic design automation tool vendors including Cadence, [9] Synopsys [10] and Silvaco [11] have released controller IP blocks and associated verification software for the implementation of the I3C bus in new integrated circuit designs.

ADMs traditionally have a high-speed side (where the full line rate signal is supported), and a low-speed side, which can consist of electrical as well as optical interfaces. The low-speed side takes in low-speed signals, which are multiplexed by the network element and sent out from the high-speed side, or vice versa.
