In 2010, a new revision of AMBA, AMBA4, defined the AXI4, AXI4-Lite and AXI4-Stream protocols. AXI is royalty-free and its specification is freely available from ARM. AMBA AXI specifies many optional signals, which can be included depending on the specific requirements of the design, [3] making AXI a versatile bus for numerous applications.
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 ...
AXI or variation, may refer to: Automated X-ray inspection; Advanced eXtensible Interface of ARM for Advanced Microcontroller Bus Architecture (AMBA) AXI car, a right-hand-drive version of the DMC DeLorean; Aeron International Airlines (ICAO airline code: AXI), see List of airline codes (A) Axitinib (PDB code AXI)
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set.
Master and Slave Wishbone's interfaces. The Wishbone Bus is an open source hardware computer bus intended to let the parts of an integrated circuit communicate with each other.
The Open Core Protocol (OCP) is a protocol for on-chip subsystem communications. It is an openly licensed, core-centric protocol and defines a bus-independent, configurable interface. OCP International Partnership produces OCP specifications. OCP data transfer models range from simple request-grant handshaking through pipelined request-response ...
Traditionally, a device has an interrupt line (pin) which it asserts when it wants to signal an interrupt to the host processing environment. This traditional form of interrupt signalling is an out-of-band form of control signalling since it uses a dedicated path to send such control information, separately from the main data path.
AX.25 (Amateur X.25) is a data link layer protocol originally derived from layer 2 of the X.25 protocol suite and designed for use by amateur radio operators. [1] It is used extensively on amateur packet radio networks.
